Fun Factory Stella: review

Fun Factory’s smallest and cheapest vibrator reviewed against the manufacturer’s own specifications, quick guide, and price data from four Swedish stores. Twelve vibration programs on a single button, 98 × 34 × 33 millimeters, 52 grams, IPX7 according to IEC 60529, and a replaceable AAA battery with about 60 minutes of runtime — plus three stores that list the wrong number of batteries and a guarantee claim that does not apply to Swedish purchases.

My rating

The simplest and most immediate product in the comparison: nine centimeters, 52 grams, one button, and a AAA battery that can be swapped in a few seconds instead of charging for three hours. Silicone against the body and IPX7 make it easy to keep clean. What you pay with is control — twelve fixed programs in a one-way loop with no separate intensity control — and a runtime of just one hour per battery. Add that the 25-year guarantee printed on the box does not apply when you buy from a Swedish retailer.

  • Twelve vibration programs, one button, no charging time
  • 98 × 34 × 33 mm and 52 g — shortest in the comparison
  • Silicone, ABS plastic, and polycarbonate according to the manufacturer
  • IPX7 according to IEC 60529 — immersion 1 m for 30 min
  • One AAA battery at 1.5 V is not included; approx. 60 min operating time
  • 214–269 SEK at four stores for the same EAN

Fun Factory Stella at a glance — here’s what you get

Fun Factory Stella is the smallest and cheapest vibrator in the German brand’s lineup, and the only one in this comparison that doesn’t charge. It’s powered by a standard AAA battery. It has a single specification line, but it determines almost everything else about the product: the price, run time, weight, the construction of the bottom cap, and how it should be stored.

The specification looks like this according to the manufacturer: length 98 millimeters, width 34 millimeters, height 33 millimeters, weight 52 grams, material silicone, ABS plastic and polycarbonate, ingress protection rating IPX7, twelve vibration programs, a single control button, and a 1.5-volt AAA battery that isn’t included but can be replaced. The quick guide states the run time as approximately 60 minutes. Fun Factory’s own list price is 24.95 euro. In Sweden, the item is sold by four retailers at prices between 214 and 269 SEK, and three of them had it in stock at the price check on September 12, 2026.

This review is exclusively about the Raspberry color with EAN 4255821802937, the manufacturer’s item number FF001089RB01. Fun Factory sells Stella in two colors, and the other one — Purple — has item number FF001089BR01 and EAN 4255821802951. The Swedish retailers alternatively call Raspberry “pink” and “Raspberry,” but all four list the same EAN, so it’s the same item.

What a bullet vibrator is, and where Stella fits within the category

A bullet vibrator is the simplest construction available in the category: a small motor with an unbalanced weight on the shaft, enclosed in a housing that vibrates as a whole. There is no sealed pressure chamber like in an air-pressure product, no flexible arm, and no other motor. In practice, the entire product is the motor’s housing, and that’s why a bullet can be made so small and so cheap.

What differentiates models within the category is essentially three things: how wide the body is, how the power is delivered, and how many steps can be selected. In width, Stella sits in the broader half. The manufacturer lists 34 millimeters, which should be compared with 22.9 millimeters for We-Vibe Tango X and 33 millimeters for ROMP Beat. In practice, this means Stella isn’t a narrow, pen-like bullet, but rather a small handle—you hold it with your whole hand instead of holding it between two fingers.

The shape is also unusual for the class. The manufacturer describes the tip as flattened and intended for G-spot stimulation, and its own infographic talks about a rounded shaft for ideal G-spot stimulation. What can be determined from the pictures is that the head bends off at a clear angle relative to the rest of the body—roughly like a full-size G-spot vibrator, but scaled down to nine centimeters. A classic bullet is straight and symmetrical.

Raspberry, Purple, and “pink”—which variant is which?

The naming around this product is messier than it needs to be, and it’s worth clearing up before you compare prices. The manufacturer calls the product STELLA only. On funfactory.com, the product type is listed as “Mini Vibrator”, while both the packaging and the quick guide say “Bullet Vibrator”. The Swedish retailers have picked up different parts of it: Joyland writes “Mini Vibrator, rosa”, Lekosmek and Taboo write “Bulletvibrator”, and Sexonic writes “Bullet Vibrator Raspberry”. Same product, four names.

  • Raspberry — the dark-pink variant that this text is about. EAN 4255821802937, item number FF001089RB01.
  • Purple — the same product in purple. EAN 4255821802951, item number FF001089BR01. Functionally identical, but with its own EAN—and therefore its own price range.

One detail that’s useful when comparing retailers: Lekosmek and Taboo both list the item number D-244193 and state the same wholesaler. That means that their product descriptions come from the same source—and that they therefore also share the same mistake, which we’ll get back to later. Joyland has its own text with its own item number, and Sexonic uses the EAN number directly as its reference.

Materials and build quality: silicone, ABS, and polycarbonate

The material question is the only characteristic of an intimate product that you can’t compensate for with experience or care, and it determines whether the product is still hygienic in a few years. Fun Factory lists three materials for Stella: silicone, ABS plastic, and polycarbonate. The same three materials are listed in the quick guide, in English as “ABS, PC, silicone”.

Where the silicone sits, and why that matters

Three materials on a product that’s nine centimeters long means they sit in different places, and the manufacturer specifies the distribution in its FAQ rather than on the product page: the toy itself is made of silicone, while the battery housing and the control element are made of body-friendly thermoplastic. Translated to Stella, that means the soft surface that you move against the body is silicone, while the bottom cap that you unscrew for the battery change and the button in the middle are the hard plastic—ABS and polycarbonate.

The important thing is that the silicone is where it should be. Silicone is non-porous, and a non-porous surface can be cleaned because there are no microscopic cavities where residues can get trapped. This is the single most important property of a material that is meant to sit against the mucous membrane. ABS and polycarbonate are also non-porous, but they are hard and therefore fit better in the construction than against the body.

What is worth noting, on the other hand, is the seam. A battery-powered product must have an opening for the battery, and that is where the silicone and the plastic meet. It’s a joint that a rechargeable, one-piece molded product does not have, and it is also the point where both water tightness and cleaning place demands. The manufacturer does not publish any information about what type of sealing is used in the lid.

Fun Factory does not publish anything about the surface’s character. The retailer Joyland describes it as silky-smooth and smooth, and states the hardness as medium. This is a store claim, not a manufacturer claim, and the manufacturer does not give any Shore value for the silicone.

Phthalates, BPA, and plasticizers — what the declaration says

Phthalates are a group of plasticizers used to make plastic — above all, flexible PVC — pliable. The Swedish Chemicals Agency describes them as substances that can affect the hormone system and make reproduction more difficult, and several of them are therefore restricted or banned within the EU. This product category is the subject of recurring supervision because it contains soft plastic against the skin and mucous membrane.

In its FAQ, Fun Factory states that all products are free from plasticizers, BPA, and phthalates, and that the silicone is hypoallergenic, non-porous, vegan, and halal. This is a clear commitment — but it applies to the entire range, not just Stella. Fun Factory does not publish any product-specific material declaration beyond the three material names for this model, and they also do not state any EU declaration of conformity together with the quick guide. The retailer Joyland states “Phthalate-free: Yes” in its own specification.

What can still be established is that silicone does not need phthalate plasticizers to become soft. The softness comes from the polymer’s own structure. Therefore, specifying silicone as the material is, in itself, a better piece of information than labels like “TPE” or “jelly rubber,” which say nothing at all about which plasticizers are included.

Dimensions and weight: 98 × 34 × 33 millimeters and 52 grams

The manufacturer states the length as 98 millimeters, the width as 34 millimeters, and the height as 33 millimeters. The weight is given as 52 grams, and the same 52 grams is listed in the manufacturer’s own product data for both color variants. That the width and height differ by one millimeter means the cross-section is not completely round, but slightly oval.

The shop details are broadly correct, but they need to be read the right way. Joyland states the length as 9.8 centimeters and the diameter as 3.3 centimeters, which corresponds to the manufacturer’s 98 and 33 millimeters. Lekosmek states 76 grams and Taboo states 86 grams. The two weight figures are shipping weights including packaging, not the product’s weight—and the fact that they also differ by ten grams from one another for the same article clearly shows that they come from the shops’ logistics systems rather than from the manufacturer’s datasheet. The manufacturer’s 52 grams is the product weight.

The size becomes interesting only when compared. We-Vibe Tango X measures 99.8 × 22.9 × 24.3 millimeters—almost exactly the same length as Stella, but eleven millimeters narrower. ROMP Beat measures 150 × 33 × 33 millimeters, so the same width but fifty percent longer. Fun Factory’s own Volita, which costs exactly the same in the manufacturer’s web shop, measures 155 × 30 × 30 millimeters and weighs 80 grams.

What those figures mean in practice is that Stella is the shortest and widest of the four. That makes it the most pocket-friendly, and the only one of them that fits into a small pouch without lying diagonally. The downside of the same thing is that a 34-millimeter width is much for a product whose tip the manufacturer describes as intended for the G-spot. Fun Factory does not publish an insertable length, and the quick guide’s own illustration shows the product held against the body from the outside.

The packaging is a hanging cardboard package with a window. The manufacturer does not publish either the packaging dimensions or a complete contents list. What you can read directly from the manufacturer’s own packaging image is that the battery is explicitly not included, and that the packaging is labeled with twelve modes, body-friendly materials, IPX7, and a warranty statement that we return to in the warranty section.

Twelve vibration programs and a single button

The interface on Stella consists of one button. It sits in the middle of the front of the body, is round, and bears Fun Factory’s FUN logo in relief. There is no other button, no display, and no LEDs that indicate which mode you’re on.

The quick guide describes operation in two steps. You turn the product on and off by holding the FUN button pressed in for 1–2 seconds. After that, you step through by making short presses of the twelve vibration programs, and the guide’s diagram shows that the stepping works in a loop: from program 1 up to program 12 and then back to 1. The manufacturer’s infographic and the packaging state the same number—twelve vibration programs and “12 modes,” respectively. The shops write “12 vibration levels” or “12 different steps,” which is the same thing.

How to step through the twelve programs

That is where the simplest design gets its clearest cost. On the Stella, intensity and pattern are not two independent controls but merged into twelve fixed steps. Which of the twelve are even intensities and which are pulsing patterns Fun Factory does not publish, neither on the product page nor in the quick guide.

Compare that with how the competitors describe the same thing. We-Vibe lists eight intensity levels and seven patterns as two separate axes for Tango X, and ROMP lists six intensity levels and four patterns for Beat. With two axes, you can increase the strength without changing the pattern. On the Stella, you change everything at once, and since the stepping only goes in one direction, you have to click through the rest of the loop to come back one step. With twelve modes, it’s up to eleven presses.

There is also an unanswered question in the manufacturer’s own material. The product page labels the Stella with the button lock function icon — the manufacturer writes "Tastensperre" — but the quick guide describes no locking function at all, only on, off, and stepping between the programs. Fun Factory’s general troubleshooting answer for button lock also assumes that you hold down both the plus button and the FUN button at the same time, and there is no plus button on the Stella. So how any possible button lock is activated on this specific model cannot be determined from the manufacturer’s documentation. This is relevant for a product whose main selling point is that it should lie in a travel case.

Clitoris or G-spot — what the flattened tip does

Fun Factory describes the tip as flattened and intended for G-spot stimulation, and the infographic talks about a rounded shaft for ideal G-spot stimulation. The Swedish stores go further and state both uses: Lekosmek writes that it’s suitable for clitoral and G-spot stimulation, Taboo that the rounded tip stimulates both the clitoris and the G-spot.

What can be established is that the geometry points to external use and limited internal use. With a width of 34 millimeters at the thickest part and a total length of 98 millimeters, it is only the curved tip that realistically reaches from the inside, and as mentioned, the manufacturer states no insertable length. The quick guide’s usage image shows the product held against the body from the outside, with a lubricant icon next to it.

The recommendation for lubricant is not a minor detail. Fun Factory states water-based lubricant in the quick guide and in its FAQ explicitly advises against silicone-based lubricant on silicone products, because it can’t be completely removed from the surface and makes the product unhygienic. Joyland states the same thing in its own specification.

How loud is the Fun Factory Stella?

The answer has to be short and honest: Fun Factory publishes no measured decibel value for Stella. It is neither on the product page, in the specification table, on the packaging, nor in the quick guide. The product’s own keywords from the manufacturer include the word "leise", meaning quiet, but it’s a label, not a measurement. None of the four Swedish stores also states any sound value.

What can be said generally about the construction is that a bullet with an unbalanced motor weight produces a higher and more buzzing sound than a linear motor, and that a small housing with hard plastic at the bottom dampens less than a large, heavy body. What that means in decibels for Stella is an estimate, and an estimate doesn’t belong in a specification table. Websites that state an exact decibel value for this model either show their own measurement or a value without a source.

A practical tip that applies regardless of model: place the product on a soft surface when you’re not holding it. A hard tabletop works like a resonance box and noticeably amplifies the sound.

The battery: one AAA — and three stores that say two

This is the clearest discrepancy between the manufacturer and the Swedish retail, and it costs money if you go by the stores’ information.

Fun Factory states a single battery, and does so in four places independently of each other. The specification table on the product page writes "1x Micro AAA", where Micro is the German designation for AAA. The infographic in the product gallery writes "1 x AAA". The packaging image writes "Battery-powered (1× AAA, not included)". And the quick guide writes "Battery Type: 1x AAA 1.5V (not included, replaceable)".

Joyland, Lekosmek, and Taboo all state two AAA batteries. Lekosmek and Taboo also share the same wholesaler item number and the same wholesaler, which explains why they have the same errors. The manufacturer wins. Practically, that means you need one battery, not two, and the product therefore becomes marginally cheaper to run than the store texts suggest. Taboo, however, describes the mechanism correctly: the battery compartment is accessed by unscrewing the bottom.

How long does a battery last in Fun Factory Stella?

The quick guide lists the operating time as about 60 minutes. It’s an hour per battery, not per charge, and the difference is the whole point of this product.

The number looks weak next to a rechargeable product until you factor in the reset. A rechargeable bullet that runs out is unusable until it’s been charged: ROMP specifies a charging time of 180 minutes for Beat, and We-Vibe specifies 90 minutes for Tango X. Stella has no charging time at all. A drained battery is replaced in a few seconds, assuming you have a new one at home—and that’s the downside, because a dead battery without a spare is just as unusable as a drained built-in battery, only without the possibility to plug in a cord.

The comparison in pure operating time looks like this: Stella about 60 minutes per battery, ROMP Beat 1 hour per charge, We-Vibe Tango X up to 2 hours per charge. So Stella and ROMP Beat are equal, while Tango X lasts twice as long. Which of the twelve programs the 60 minutes are measured for, Fun Factory does not state, and that applies to all three manufacturers as well.

The other side of battery operation is lifespan. A built-in lithium-ion battery loses capacity with the number of charge cycles, and when it’s used up, the product is effectively spent because the cell is permanently soldered in place. Stella has no built-in battery that can age. Instead, what limits lifespan is the motor, the seal in the bottom cap, and the condition of the silicone—and two of the three can be influenced with care.

Which battery should you buy for Fun Factory Stella?

An alkaline AAA at 1.5 volts. Fun Factory is explicit about this in its FAQ: use standard 1.5-volt batteries for battery-powered products, not rechargeable cells. The reason is voltage—a rechargeable NiMH cell in AAA format provides 1.2 volts, i.e. twenty percent less, which you can notice right away in the motor’s performance.

The manufacturer provides two instructions that rarely appear in store texts. The first is that the battery should be removed after use and that the battery compartment should be left open. This is about both leakage from alkaline cells that are left in for a long time and about letting the compartment dry. The second is troubleshooting: if the product starts by itself as soon as you screw the lid back on, the battery is inserted the wrong way—this is not a fault with the product.

Water resistance: IPX7 and the lid that must be fitted correctly

Fun Factory states IPX7 for Stella in three places: in the specification table, on the packaging, and in the quick guide. The rating comes from the international standard IEC 60529, which defines enclosure classes for electrical equipment.

What IPX7 means according to IEC 60529

The 7 in the second position means the product is tested for immersion in water to a depth of one meter for 30 minutes. So it’s not a splash protection rating but a real immersion rating: the entire product can be rinsed off under running water, and it works in the shower and bathtub. The quick guide’s cleaning image also shows the product immersed in a container of water.

There is, however, a condition that applies specifically to battery-powered products, and Fun Factory states it in its FAQ: the battery-powered products are waterproof as long as the battery compartment is properly closed. That’s a real difference compared with a rechargeable product with magnetic charging and an entirely sealed housing, where there is no opening at all. On Stella, the waterproof rating depends on you having screwed the bottom back on all the way, and on the seal there still being intact. If you don’t screw it shut properly, the IPX7 rating is without effect.

This store claim needs to be corrected here. Taboo contradicts itself: the page’s body text states “Waterproof (IPX5)” while the properties list just below states “Waterproof IPX7”. IPX5 is a completely different class—it covers water jets, not submersion. The manufacturer’s information applies, and the manufacturer writes IPX7 in three places.

Cleaning, lubricant, and storage

Fun Factory recommends warm water and mild soap, or a cleaning product intended for silicone products. Clean before and after each use, and also before the very first use. Remove the battery before you wash the product, and let both the battery compartment and the threads dry before you screw it back together.

When it comes to lubricant, the manufacturer is more specific than most. A silicone-based lubricant should never be used on silicone products, because it can’t be removed completely and makes the surface unhygienic. Fun Factory also explicitly warns against oils and creams—sun oil and sunscreen, lip balm and lipstick, essential oils, coconut oil, and all types of cooking oils—and states that they can cause irreversible damage to the control element and to the entire product, and that using them risks voiding the warranty coverage. It’s an unusually specific warning, and it’s worth taking seriously.

In the quick guide, storage has two limits. The storage temperature is specified as between −5 and +60 degrees, which rules out boiling and dishwasher cleaning despite the IPX7 rating, and the storage image shows the product in a bag with a crossed-out picture of sharp objects next to it. The manufacturer does not publish a list of what the packaging contains, so if a storage bag is actually included, it can’t be determined from the manufacturer’s materials—at any rate, the battery doesn’t help either.

The quick guide also includes a safety text that rarely shows up in stores: remove piercings and jewelry in the genital area before use, do not use the product on irritated or damaged skin, stop if pain or discomfort occurs, and do not put the product into use if it is unusually hot, mechanically damaged or deformed, or if it has changed color.

Fun Factory Stella compared with the alternatives

Three comparisons are relevant: against Fun Factory’s own battery-powered model in the same price range, against the rechargeable bullet that is the reference in the class, and against a rechargeable competitor that sits in the same Swedish price bracket. All the information below comes from each manufacturer’s own specifications.

Against Fun Factory Volita — same price, almost twice as long

Volita is Fun Factory’s other battery-powered model and costs exactly the same in the manufacturer’s web store: 24,95 euro, the same as Stella. It’s also IPX7 and powered by a single battery as well. That’s where the similarities end.

Volita measures 155 × 30 × 30 millimeters and weighs 80 grams, versus Stella’s 98 × 34 × 33 millimeters and 52 grams. So Volita is 57 millimeters longer, 4 millimeters narrower, and 28 grams heavier. The battery is also different: Volita uses an AA battery, i.e. the larger format, while Stella uses AAA. The material is listed as silicone and ABS plastic for Volita, while Stella also has polycarbonate on the list.

The choice between them is not about price but about shape and use. Volita is an elongated, narrow wand—a classic mini vibrator. Stella is a short, wide grip with a curved tip. If the product is going to be in your carry-on bag or in the bedside drawer, Stella is the less discreet one. If you want something you can keep at a distance from your hand, or something that reaches farther, then Volita is the right model. The manufacturer doesn’t state a run time for Volita, so a comparison on that point can’t be made.

Against We-Vibe Tango X — the same length, but rechargeable

Tango X is the bullet that the rest of the class is usually measured against, and it’s interesting precisely because it’s almost exactly the same length as Stella: 9.98 centimeters versus 9.8. Otherwise, they are opposites.

We-Vibe states a 22.9-millimeter width versus Stella’s 34, a USB-charged lithium-ion battery with up to two hours of run time and a 90-minute charging time, eight intensity levels and seven patterns with separate axes, a travel lock described in detail, ABS material and body-friendly silicone free from phthalates, BPA, and latex, an IPX7 ingress protection rating, and a two-year warranty.

The differences that actually matter are three. Tango X lasts twice as long and doesn’t use any batteries, but it does require a charging cable and 90 minutes when it’s empty. Tango X gives you two independent controls instead of a single ring with twelve fixed steps. And Tango X is 11 millimeters narrower, which makes it a real bullet while Stella is a small handle. What Stella still has is immediacy: you can take it with you without a charging cable and get it ready to use with a battery from the store, anywhere in the world.

Against ROMP Beat — the same run time, but without having to buy batteries

ROMP Beat is the most direct competitor in Swedish retail because it’s in the same price range as Stella. ROMP lists the dimensions as 150 × 33 × 33 millimeters—meaning the same width as Stella but 50 percent longer—with body-friendly silicone in the head and an IPX7 ingress protection rating.

The controls are arranged as on We-Vibe: six intensity levels and four patterns, controlled with a single button just like on Stella, with shutoff by holding the button for two seconds. The battery is rechargeable with the included USB cable; the runtime is listed as one hour and the charging time as 180 minutes. The warranty is two years.

This comparison is the sharpest of the three, because the runtime is the same—one hour—but the turnaround is different. ROMP Beat requires three hours of charging, while Stella requires a new battery. Economically, ROMP Beat is cheaper to run in the long run because you never buy replacement batteries; practically, Stella is faster to get back into service. And in terms of features, ROMP lets you change the strength without changing the patterns, which Stella doesn’t do.

Price range: 214 to 269 SEK at four stores

Four Swedish retailers sell the item with EAN 4255821802937. The lowest price in the feed is Sexonic at 214 SEK; the highest is Lekosmek and Taboo at 269 SEK each. That’s a difference of 55 SEK, or a little over 25 percent, for the exact same item number, the same color, and the same packaging.

However, the inventory situation changes the picture. Sexonic was the only one of the four that lacked available stock in the product feed at the price check on September 12, 2026, which means that the cheapest price wasn’t the cheapest available price. Among the three that had the item in stock, Joyland was the cheapest at 249 SEK, with Lekosmek and Taboo twenty kronor higher. So the difference you can actually buy for is 20 SEK, not 55. Sexonic’s own product page also showed an in-stock figure at the same time—an inconsistency between the feed and the store page that’s worth knowing about, and a reason to check the stock status in the store before you count on the lowest price.

The price spread isn’t because any store sells a different variant. All four list EAN 4255821802937, and Lekosmek and Taboo also state the same wholesale item number, D-244193. So it comes down to the stores’ own margin-setting on a product that sits close to the manufacturer’s own list price of 24.95 euro.

Two things belong in the price reasoning. The first is the battery: it’s not included, and this applies regardless of store. The second is shipping. In this price range, the order value is below the threshold for free shipping at most Swedish stores, which means the shipping fee can be larger than the entire price difference between the cheapest and the most expensive store. Always check the final total at checkout, not just the product price in the table above.

Who is Fun Factory Stella for—and who isn’t?

It fits you if you want something small and uncomplicated from an established brand, without having to keep track of an additional charging cable. Nine centimeters, 52 grams, and a single button make it one of the simplest products in the category to just pick up and use. IPX7 means it can be rinsed under the tap and comes along into the shower, and battery operation makes it just as useful in a hotel room as at home. It also fits you if you want silicone against your body rather than hard plastic, and you prefer a curved tip over a straight shaft.

It’s not for you if you want fine-tuning. Twelve fixed programs in a one-way loop, without separate intensity controls, offer less control than both We-Vibe Tango X and ROMP Beat for about the same money. It’s not for you if you dislike buying batteries, or if you want an fully molded product without a screw seam—its water resistance for Stella depends on the bottom cap being properly sealed. It also isn’t for you if you require published measurements before purchase, since Fun Factory does not publish sound level, insertable length, or which of the twelve programs are patterns and which are even intensity levels.

One more thing belongs in the decision. Stella is designed as a second product, not as a main product. The size, the replaceable battery, and the price tag all point in the same direction: this is the product you keep lying around in your toiletries bag or lend out without it being something you’re afraid to run out of. As the only product in the box, it’s thin on features—and then a rechargeable model with two controls is a better investment in the same price range.

Warranty, complaints, and right of withdrawal — 25 years or 24 months?

Here is the single most important thing a Swedish buyer should know about this product, and it’s easy to miss.

The manufacturer’s packaging is labeled with “25-year guarantee,” and the retailer Taboo repeats it verbatim in its product text: “25 years guarantee from Fun Factory.” Fun Factory’s own FAQ specifies that the 25-year warranty only applies to products that are purchased directly from Fun Factory — meaning via their own web shop or in their previous own stores — with proof of purchase via a receipt. For Fun Factory products otherwise, the manufacturer states a 24-month warranty in the same FAQ.

Fun Factory also makes it clear who you should contact: complaints about products that were not purchased directly from them are not handled by the manufacturer, but must be directed to the seller. So if you buy from any of the four Swedish stores in the table above, it’s the store that is your point of contact, and the 25-year promise on the box doesn’t apply to you.

The guarantee also has an exception rule that’s worth reading before you open the first bottle of lubricant. Fun Factory states that using oils and creams—sunscreen oil and sun cream, lip balm and lipstick, essential oils, coconut oil, and all kinds of cooking oils—can cause irreversible damage to the control element and to the entire product, and that you risk losing your guarantee right if they are used together with a Fun Factory product. The same applies to silicone-based lubricant on the silicone surface.

What always applies, however, are your statutory rights, and they are stronger than the manufacturer’s 24 months. Under the Swedish Sale of Goods Act (konsumentköplagen), you have three years to complain if the item is faulty, regardless of what the manufacturer promises. For distance purchases, you also have a right of withdrawal for fourteen days under the Act on distance contracts and contracts outside business premises (lagen om distansavtal och avtal utanför affärslokaler). Be aware that in practice the right of withdrawal is limited for hygiene products that have been taken out of a sealed package—however, the right to complain about faults always applies. If you have questions about what applies in your case, Konsumentverket (Swedish Consumer Agency) guides you via Hallå konsument.

Frequently asked questions about Fun Factory Stella

How many batteries does Fun Factory Stella need — one or two?
One. Fun Factory specifies a single 1.5-volt AAA battery in four places, independently of where you look: in the specification table on the product page (1x Micro AAA), in the infographic in the product gallery (1 x AAA), on the packaging (Battery-powered, 1× AAA, not included), and in the quick guide (Battery Type: 1x AAA 1.5V, not included, replaceable). Three of the four Swedish shops — Joyland, Lekosmek, and Taboo — instead list two AAA batteries. The manufacturer’s statement applies. Lekosmek and Taboo also share the same wholesale item number, which explains why they have the same mistake in the text.
How long does the battery last in Fun Factory Stella?
The manufacturer’s quick guide states an operating time of about 60 minutes. This is per battery, not per charge, because the product isn’t charged. For comparison, ROMP lists an operating time of one hour and a charging time of 180 minutes for Beat, and We-Vibe lists up to two hours of operating time and 90 minutes of charging time for Tango X. The advantage of Stella is that there is no charging time at all — an empty battery is replaced in a few seconds. The downside is that you need to have a new battery at home, and the battery isn’t included in the package. The manufacturer doesn’t say for which of the twelve programs the 60 minutes are measured.
Is Fun Factory Stella waterproof?
Yes, it’s rated IPX7. According to the IEC 60529 standard, that means the product has been tested for submersion in water to a depth of one meter for 30 minutes, and the manufacturer lists IPX7 in the specification table, on the packaging, and in the quick guide. One condition applies, though: Fun Factory writes in its FAQ that the battery-powered products are waterproof as long as the battery compartment is properly closed. Also note that Taboos product text contradicts itself — the body text states IPX5, while the feature list on the same page states IPX7. The manufacturer’s information is IPX7. Storage temperature is −5 to +60 degrees, which rules out boiling and the dishwasher.
How do you turn off Fun Factory Stella and change the vibration program?
With the product’s only button, the FUN button on the front. The quick guide states that you start and turn it off by holding the button down for 1–2 seconds, and that short presses cycle through the twelve vibration programs in a loop from 1 to 12 and back to 1. There is no separate intensity control, which means that intensity and patterns change at the same time, and because the cycling only goes in one direction, you have to click through the rest of the loop to go back one step. The product page labels the model with an icon for button lock, but the quick guide doesn’t describe any lock function, and the manufacturer’s general instructions assume a plus button that Stella doesn’t have.
Does Fun Factory’s 25-year warranty apply if I buy Stella from a Swedish store?
No. The packaging is labeled with a 25-year warranty, and the retailer Taboo repeats it in its product text, but Fun Factory’s own FAQ specifies that the 25-year warranty only applies to products that are purchased directly from Fun Factory — via their own webshop or at their previous own stores — with proof of purchase (receipt). For other Fun Factory products, the manufacturer lists a 24-month warranty, and complaints about products that were not purchased directly from them are handled by the seller, not the manufacturer. If you shop with a Swedish retailer, the store is your counterparty. Regardless of warranty, you have a three-year right to make a complaint under konsumentköplagen (Swedish Consumer Sales Act).
What’s the difference between Fun Factory Stella and We-Vibe Tango X?
They’re almost exactly the same length — 9.8 centimeters vs. 9.98 — but otherwise they’re opposites. Tango X is 22.9 millimeters wide versus Stella’s 34 millimeters; it has a USB-charged lithium-ion battery with up to two hours of runtime and a 90-minute charging time, and it splits the controls into eight intensity levels and seven patterns. Stella is powered by an AAA battery with about 60 minutes of runtime and has twelve combined programs on one button. Both are IPX7, and both have silicone on the part that touches the body. If you choose based on control and runtime, Tango X wins. If you choose based on not having to use a charging cable and being able to make the product ready to use with a battery anywhere, Stella wins.
Which lubricant can be used with Fun Factory Stella?
Water-based. The quick guide recommends lubricants, and Fun Factory explicitly advises in its FAQ against using silicone-based lubricant on silicone products, because it can’t be completely removed from the surface and makes the product unhygienic. The manufacturer also specifically warns about oils and creams — tanning oil and sunscreen, lip balm and lipstick, essential oils, coconut oil, and all kinds of cooking oils — and writes that these can cause irreversible damage to the control element and to the entire product, and that the warranty claim may be lost if they’re used. Clean with warm water and mild soap, or with a cleaner intended for silicone products.
Why does the price differ between the Swedish stores?
The same item with EAN 4255821802937 costs 214 SEK at the cheapest store in the feed and 269 SEK at the most expensive — a difference of 55 SEK, or a little over 25 percent. It doesn’t depend on different variants: all four stores list the same EAN, and Lekosmek and Taboo also state the same wholesale item number D-244193. Inventory status does, however, change the picture, because the cheapest store lacked stock availability in the product feed at the time of the price check. Of the three stores that had the item at home, Joyland was the cheapest at 249 SEK, and the other two were at 269 SEK — a difference of 20 SEK. Also factor in shipping, which in this price range can exceed the entire price difference.

I run the site myself and have reviewed 395 products since 2023. Before that, I worked for eight years as a buyer of intimate hygiene products, and that’s where the product knowledge comes from. Each review is based on the manufacturer’s own specifications, product data sheets, and price data from all the shops that sell the product — all sources are at the very bottom of the page and can be checked. I compare the models against each other based on what can actually be verified: materials, dimensions, intensity levels, water-resistance rating, warranty, and price. If you find an error, I want to know about it.
