Fun Factory Stronic Surf: review

Fun Factory’s wave-profiled pulsator reviewed against the manufacturer’s own specifications, quick guide, and price data from five Swedish shops. Ten shock programs spread across seven speeds and three patterns, 205 × 47 × 38 millimeters, a 900 mAh lithium-ion battery, IPX7 according to IEC 60529, and charging via standard USB-C — but only about 40 minutes of runtime per charge.

My rating

One of the few products where the thrust movement is the actual function and not an add-on, and the only one in Fun Factory’s pulsator family where the manufacturer publishes the full battery data. 900 mAh, IPX7, and standard USB-C are strong points. What you pay for is runtime: about 40 minutes per charge versus about three hours of charging time, plus a charging cable that is not included in the box.

  • Ten thrust programs — seven speeds plus three patterns
  • 205 × 47 × 38 mm and 294 g, widest in the Stronic family
  • Li-ion 3.7 V, 900 mAh — approx. 40 min runtime, approx. 3 h charging
  • IPX7 according to IEC 60529 — immersion 1 m for 30 min
  • USB-C, but the charging cable is not included
  • 506–695 SEK at five stores for the same EAN

Fun Factory Stronic Surf in brief — this is what you get

Fun Factory Stronic Surf is a pulsator, not a vibrator. The difference is not marketing—it’s mechanical: instead of shaking the material with an unbalanced weight, a linearly driven mechanism pushes the entire shaft back and forth. The manufacturer calls the principle Stronic technology and describes it as a toy that pushes itself away. It’s the only characteristic that truly distinguishes this product category from everything else in the vibrator shelf, and it’s also why the specification looks different—especially in the line for run time.

According to Fun Factory, the specification looks like this: ten thrust programs split across seven speed levels and three patterns, enclosure rating IPX7, a lithium-ion battery of 900 mAh and 3.7 volts, about 40 minutes of run time, about 3 hours of charging time, and charging via USB-C. The dimensions are 205 × 47 × 38 millimeters and the weight is listed as 294 grams. The product has a touch lock for transport. In Sweden, the item is sold by five stores at prices between 506 and 695 SEK, and four of them had it in stock at the price check.

This review is exclusively about the Dark Violet variant with EAN 4255821802401, the manufacturer’s item number FF000994DV01. The number is matched against the variant table in the manufacturer’s own product data, where that specific item number carries the barcode. Check the EAN when comparing prices, since several stores mix up Stronic models on the same category page and because Fun Factory is also selling at least four closely related pulsators at the same time.

What is the difference between a pulsator and a vibrator?

A vibrator transfers movement as vibrations. A motor with an eccentric weight rotates, the entire housing shakes, and it’s that shaking that reaches the skin. The frequency is high and the movement amplitude is small—some fraction of a millimeter. A pulsator does the opposite: the movement is slower, but the stroke length is long enough to move the whole product relative to the body. Fun Factory states it plainly on the product page—Stronic Surf is neither a vibrator nor a dildo, but a pulsator that thrusts forward and backward by itself at different speeds and rhythms.

What you can establish purely from a technical standpoint is that this design costs energy. Moving 294 grams back and forth requires more effort than vibrating the same mass in place, and you can see it right away in the battery figures: according to the manufacturer, 900 mAh is enough for about 40 minutes. A typical silicone vibrator in the same price range often states one to two hours on significantly smaller cells. So runtime is not a sign of a bad battery, but of what the movement actually costs. Still, it’s a figure you need to take into account in your decision, and it comes up again further down.

A second consequence is the shape. Since the movement has to happen along the product’s lengthwise direction, the grip needs to be rigid and the center of gravity needs to sit at the end of the handle—where the battery and drive are located. That’s why the Stronic models look the way they do: a wide, rounded handle in hard plastic and a narrower, softer shaft. The manufacturer’s functional graphic points out the ergonomic shape as the prerequisite for hands-free use—meaning the product should be able to lie still against or in the body and work without being held.

Surf, Dive, Real, Wave, or Smooth— which Stronic is which?

Fun Factory sells several pulsators at the same time, and the names say nothing about size or power. The following applies according to the manufacturer’s own product pages, and the differences are bigger than the store category names suggest.

  • Stronic Surf — the model this text is about. 205 × 47 × 38 millimeters, 294 grams, ten shock programs. Heavily wave-profiled shaft and a curved tip.
  • Stronic Dive — the smallest in the comparison: 190 × 45 × 37 millimeters, 232 grams, and eight shock programs. Smaller battery and shorter runtime.
  • Stronic Real — the slimmest: 202 × 40 × 35 millimeters, 275 grams, ten shock programs. A realistic shape instead of a wave profile.
  • Stronic Wave — the longest of the slim ones: 211 × 41 × 41 millimeters, 276 grams, ten shock programs.
  • Stronic Smooth — the largest and heaviest: 216 × 45 × 38 millimeters and 328 grams, ten shock programs. Smooth instead of structured.

Surf is therefore in the middle of the family in terms of length, but it shares the widest measurement, 47 millimeters, with no other—it is the widest of the five. That is the piece of information that matters most in practice, because it’s the width and not the length that determines how a plug-in product feels. If you want the same technology in a slimmer format, Stronic Real is 7 millimeters narrower and Stronic Wave is 6 millimeters narrower.

Material and build quality: three plastics in one product

The material question is the only feature of an intimate product that can’t be compensated for with experience or care, and it determines whether the product will still be hygienic in five years. There’s also a detail here worth stopping to consider, because the manufacturer itself describes the material in two different ways depending on where you read it.

What silicone, ABS, and PC do in the same product

The product page states “soft, body-friendly silicone” without any reservations. The quick guide’s specification page is more precise and lists three materials: ABS, PC, and silicone. There’s no contradiction—it’s a division: the silicone sits on the shaft, meaning the part that is in contact with the body, while the handle with the battery, buttons, and charging contact is made of hard plastic. Fun Factory’s FAQ says the same thing plainly: the toys are made of medical-grade silicone, while the battery housing and control section are made of body-friendly thermoplastic.

This division has both an advantage and a disadvantage. The advantage is that the hard plastic provides the stiffness that a linear drive requires—a handle made entirely of silicone would flex with the movement and absorb part of the impact. The disadvantage is that there is a seam between the silicone and the plastic. Seams collect residue, and that transition is the only point on the product where you need to be especially careful when cleaning. The manufacturer’s own detailed image of the charging contact shows how that part is implemented: the socket is located at the bottom of the handle behind a red rubber sealing tab, and it’s that tab that makes the IPX7 rating possible despite an opening in the housing.

Silicone itself is a non-porous material. A non-porous surface can be cleaned, because there aren’t microscopic voids where residue can get trapped. That is the single most important property of a material that is meant to lie against mucous membranes, and that’s why the material declaration weighs more heavily than almost all other lines in a specification. And since the shaft is also heavily wave-profiled, there are more surfaces to rinse off, but no enclosed voids—the waves are soft and open, not channels.

Phthalates, BPA, and plasticizers—what the manufacturer commits to

Phthalates are a group of plasticizers used to make plastic—above all, flexible PVC—pliable. The Swedish Chemical Agency (Kemikalieinspektionen) describes them as substances that can affect the hormonal system and make reproduction harder, and several of them are therefore restricted or banned within the EU in a large number of products. This product category is repeatedly the subject of supervision because it contains soft, molded plastic against the skin.

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. The manufacturer’s packaging also bears the BODY SAFE MATERIALS symbol. It’s a clear-cut declaration, unlike terms such as “TPE” or “jelly rubber,” which say nothing at all about which plasticizers are included. Silicone doesn’t require phthalate plasticizers to become soft—the softness comes from the polymer’s own structure.

One thing that Fun Factory is unusually clear about, and which deserves to be included right here: the manufacturer explicitly warns that oils and creams can cause irreversible damage to the control part and to the entire product, and lists sun oil, sunscreen, lip balm, essential oils, coconut oil, and all kinds of cooking oils. According to the same text, you risk losing your right to the guarantee if you use them together with the product. It’s a tougher formulation than most manufacturers use, and it’s worth taking seriously.

Measurements and weight: 205 × 47 × 38 mm — and what the shops say

The manufacturer states the length as 205 millimeters, the width as 47 millimeters, and the height as 38 millimeters, and also the weight as 294 grams. The fact that the width and height differ is because the shaft is not round, but has a clearly oval, wave-profiled cross-sectional shape.

The shops fill in what the manufacturer leaves out, and they don’t do it entirely consistently. The manufacturer does not publish an insertable length. The retailer Joyland specifies total length as 20.3 centimeters, penetrating length as 13.5 centimeters, and diameter as 4.5 centimeters. Vuxen and Blush Me both state the total length as 20 centimeters, meaning rounded down from the manufacturer’s 205 millimeters, while Joyland’s 20.3 centimeters rounds up. Sexonic and SexleksakerOutlet publish no measurements at all. The differences are small, but they illustrate a point: when you compare two shops, you often end up comparing two different rounds of the same manufacturer specification, rather than two measurements.

The information about penetrating length is the only one that adds anything new. 13.5 centimeters out of 205 millimeters means that about two thirds of the product is the shaft and one third is the handle. Since the movement happens along the length direction, it also means that the effective reach is shorter than the total length suggests—part of the stroke is used to move the product itself. How long the stroke is in millimeters, and how many thrusts per minute the different speed steps provide, is not published by Fun Factory. This is the most noticeable gap in the specification for this product category, because stroke length and thrust frequency are exactly what distinguishes one pulsator from another.

294 grams is a lot for a handheld product of this size, and it’s a direct result of the design: both the battery and the linear drive are in the handle. If you compare within the same family, Stronic Dive is the lightest at 232 grams, and Stronic Smooth is the heaviest at 328 grams. So Surf is in the middle. Weight isn’t just a downside—part of the mass in the handle is what makes the thrust feel in the shaft instead of only shaking your hand—but it only becomes noticeable if the product needs to be held up for a longer time.

Ten pulse programs and three buttons

The interface is stripped down. The manufacturer’s product images show three buttons on the top side of the handle: a minus button at the top, the red FUN button in the middle, and a plus button at the bottom. The quick guide page for modes names the function "Thrusting intensities / programs" and shows how the plus button steps upward from 1 to 10 and the minus button steps downward from 10 to 1. The FUN button turns on and off, and it is activated with a press for 1–2 seconds.

So it’s a single control for everything. You scroll linearly through ten steps and there is no separate button for pattern selection. The advantage is that you can learn the interface in a couple of seconds without looking. The disadvantage is that you have to step through the speeds to get to the patterns—and vice versa—there’s no shortcut back to the step you liked.

Seven speeds plus three patterns — not ten speeds

This is the detail that store texts handle most carelessly. The manufacturer’s marketing states "10 thrust programs," and that’s correct—but the quick guide’s specifications page clarifies how the ten are divided: seven speed steps plus three patterns. Joyland, Vuxen, and Blush Me all state the same breakdown in their product texts: seven speeds and three rhythms, which is an unusually clear example of when the store and the manufacturer actually say the same thing.

The difference matters in practice. Seven steps of increasing speed is a short scale—fewer than the fourteen or fifteen steps that are common on air-pressure products—but on a pulsator the number of steps is less relevant than it is on a vibrator. The speed of a thrust movement can’t be cranked up indefinitely, because the stroke length is fixed and the mechanics have to have time to reverse. The three patterns are therefore not decoration but the only path to a movement that isn’t even. What the three patterns consist of—what the rhythm looks like, how long each sequence is—Fun Factory doesn’t publish.

For comparison, the manufacturer specifies for Stronic Dive four speed steps plus four patterns, meaning eight programs with the emphasis shifted toward rhythms instead of speeds. Stronic Real and Stronic Wave are both said to have ten thrust programs, but the manufacturer doesn’t specify the breakdown on their product pages.

Travel lock and how you start the product

Fun Factory describes a travel lock on the product page and justifies it by saying that Stronic Surf can be stored safely without having it start at inappropriate times. Joyland calls the same function travel lock in its store text. It’s one of the few functions in this product category that is purely practical rather than experience-based, and it’s more relevant here than on a vibrator: a product that moves itself in the bag sounds significantly more than one that just buzzes.

Getting started is simple according to the quick guide—press and hold the FUN button for 1–2 seconds to start and turn off. The guide also recommends lubricant already in the usage section, which is reasonable for a product with a profiled surface.

What hands-free actually means here

The manufacturer highlights hands-free as the main selling point, and the packaging carries the HANDS-FREE FUN symbol. What can be established is that the claim is based on two specific design choices, not a feature: partly that the movement is generated internally and therefore doesn’t require that someone moves the product, and partly that the ergonomic shape with the wide handle is intended to keep the product in place. The manufacturer’s infographic points out that ergonomic shape as the prerequisite.

At the same time, it’s worth being clear about what that entails. A pulsator without a sling or a suction cup is held in place by the body and by the center of gravity—nothing else. Fun Factory discloses no mechanism beyond the shape, and the specification includes no attachment, no base, and no strap. Hands-free should therefore be read as “doesn’t need to be moved,” not as “stays guaranteed where you place it.”

Sound level: what Fun Factory says and what they don’t say

Joyland writes in its product text that Stronic Surf works surprisingly quietly despite its power. This is a shop statement, not a manufacturer statement, and it should be read as such. Fun Factory publishes no measured decibel value for Stronic Surf, either on the product page, in the quick guide, or on the packaging. None of the five Swedish shops publishes any measured figure either.

What you can, however, reason about is the principle. A pulsator has a mechanical movement with a long stroke length and a reversal point at each end of the stroke, and that reversal point is a sound source that a rotating vibrator motor does not have. On the other hand, the frequency is much lower. You can’t calculate what the combined result will be in decibels from the specification, and every site that provides an exact number for this model either gives its own measurement or a value without a source from the manufacturer.

A practical tip that applies regardless of model—and that matters more here than with a vibrator—is: never place the product on a hard tabletop while it’s running. A pulsator that moves lengthwise against a hard surface will knock, and the tabletop works as a resonance box.

Water resistance: what IPX7 actually means

Fun Factory Stronic Surf is rated IPX7 on the product side, in the quick guide, and with a symbol on the packaging. The rating comes from the international standard IEC 60529, which defines enclosure classes for electrical equipment. The number 7 in the second position means that the product is tested for submersion in water to a depth of one meter for 30 minutes. Fun Factory’s FAQ states the same thing in plain language: all rechargeable products from the manufacturer are completely waterproof.

IPX7 versus “splash-proof” — the deciding difference

The difference versus a splash-proof product is greater than the wording suggests. Splash protection covers water droplets and, at best, water jets, but not submersion. Such a product can handle a damp cloth and possibly a shower, but not a bathtub, and it should not be held under running water without thinking about the buttons and the charging connection.

With IPX7, the entire product can be rinsed off without being careful. There is, however, a condition that is specific to this design and that none of the stores mention: the sealing tab over the USB-C port must be securely in place before the product meets water. The manufacturer’s detail image shows a red rubber flap that is folded down over the port at the bottom of the handle. An enclosure rating applies to the product in the closed position, not with the flap open. If a product is missing an IPX specification entirely, it should be treated as not waterproof — the absence of a rating is never a sign that the product would be approved.

Cleaning, lubricant, and storage

The quick guide’s cleaning page shows the product submerged in water together with a cleaning agent — in other words, water plus toy cleaner, not just wiping. Rinse off after every use; be especially careful in the waves on the shaft and in the seam between silicone and hard plastic; wipe off and let it air-dry before putting the product away.

The lubricant question is settled by the manufacturer: water-based. Fun Factory’s FAQ states that all suitable lubricants work as long as they are water-based, and it also explicitly warns against oils and creams of all kinds, referring to the risk of irreversible damage to the control section — and that the warranty right may be lost. A silicone-based lubricant should not be used on silicone products either: it breaks down the silicone surface over time and makes it porous, and a porous surface can no longer be cleaned properly — only replaced.

Storage has its own line in the specification. The manufacturer states a storage temperature of −5 to +60 degrees Celsius, and the quick guide’s storage page also shows that the product should not be stored together with sharp objects. The temperature limit rules out boiling water and dishwashers despite IPX7 — it’s the same limitation that applies to all products with a built-in lithium-ion battery.

Battery and charging: 900 mAh, 40 minutes, three hours

Fun Factory publishes unusually complete battery data for this product, and it’s worth noting because several larger brands don’t. The quick guide lists the battery type as lithium-ion at 3.7 volts, capacity 900 mAh, maximum charging current 500 mA, charging voltage 5 volts, charging time of about 3 hours, and operating time of about 40 minutes.

How do you charge Fun Factory Stronic Surf?

Via USB-C. The port is located at the bottom of the handle behind the red sealing flap, and the manufacturer states on the product page that the model is rechargeable via USB-C. The charging cable is not included. It is explicitly stated in the quick guide’s charging section — "USB-C charging cable not included" — and three of the Swedish stores repeat it in their product texts, adding that any USB-C standard cable works.

It’s a trade-off that goes in different directions. The downside is obvious: you pay for a product you can’t charge out of the box unless you already have a cable at home. The advantage is that the cable is completely replaceable. If you lose it, a replacement costs a few tens of SEK at the nearest store, unlike the magnetic, product-specific charging cables that several competing brands use and that can only be bought from the manufacturer.

There is also a conflict between the sources that’s worth reporting. Joyland writes in its product text that the pulser is charged via Fun Factory’s magnetic USB cable. The manufacturer’s product page, the quick guide, and the detailed image of the charging connector all show a USB-C port without a magnetic mount, and Vuxen, Blush Me, and SexleksakerOutlet all state that it is USB-C. The manufacturer wins. Joyland’s text is very likely describing an earlier generation of Stronic Surf, which used Fun Factory’s magnetic charging solution. Expect USB-C and check at checkout if you order it there.

Why does 900 mAh only last 40 minutes?

900 mAh at 3.7 volts corresponds to approximately 3.3 watt-hours of stored energy. That this amount lasts for about 40 minutes means an average power output of around 5 watts, which is high for a handheld product. The comparison within the family shows the same pattern: Stronic Dive has 500 mAh and is stated to last about 30 minutes, so it’s in the same order of magnitude per milliamp-hour. It’s not that the battery is small — it’s that the movement is expensive.

The relationship between charging time and operating time is the figure that deserves the most attention before buying: about 3 hours of charging gives about 40 minutes of operation. That’s about 4.5 minutes of charging per minute of use. For someone who uses the product once in a while, it doesn’t matter, but the person who wants to have it available spontaneously needs to charge it routinely rather than only when needed.

What generally applies to lithium-ion batteries also applies here: capacity drops with the number of charge cycles, and the manufacturer does not state anywhere that the battery would be replaceable—the quick guide lists it as an integrated part of the product. With the short operating time, it’s especially important not to store the product completely discharged for long periods. A maximum charging current of 500 mA also means that a more powerful fast charger is of no benefit; the product draws whatever it draws regardless of what the charger can handle.

Fun Factory Stronic Surf compared with the alternatives

The most relevant comparisons are within the same brand, because Fun Factory is the manufacturer that consistently publishes complete battery data for its pulsators and therefore the only one where the figures can actually be compared directly. All the information below comes from the manufacturer’s own product pages and quick guides, and all prices come from the shops’ product feeds on July 29, 2026.

Against Fun Factory Stronic Dive — 19 SEK for twice as much battery

Stronic Dive costs from 487 SEK, i.e. 19 SEK less than Stronic Surf at its cheapest. In practice, the price difference is zero, but the specifications differ more than the price tags suggest.

Dive measures 190 × 45 × 37 millimeters and weighs 232 grams—it's 15 millimeters shorter, 2 millimeters narrower, and 62 grams lighter. The battery is 500 mAh versus Surf’s 900 mAh, and the operating time is stated as about 30 minutes versus about 40. The charging time is the same, about 3 hours. The number of programs is eight versus ten, and the breakdown differs: Dive has four speed steps plus four patterns, Surf has seven speed steps plus three patterns. Both are IPX7; both are ABS, PC, and silicone; both charge via USB-C.

The conclusion is unusually clear for a comparison between two closely related models: for the same money, on Surf you get a battery that’s 80 percent larger, 33 percent longer operating time, and two more programs. What you pay with is 62 grams and 15 millimeters. If you want the smallest and lightest pulsator in the lineup, Dive is the answer; in every other respect, Surf is the better deal at these prices.

Against Fun Factory Stronic Real — same price, 7 millimeters narrower

Stronic Real costs from 506 SEK, i.e. exactly the same lowest price as Stronic Surf. Real measures 202 × 40 × 35 millimeters and weighs 275 grams. It has ten shock programs, is IPX7, and charges via USB-C—on paper, the same product.

What sets them apart is the shape and the width. Real is 7 millimeters narrower and 3 millimeters lower, with a realistically shaped surface instead of Surf’s strong wave profile. The difference of 7 millimeters in width is the single most important detail in the entire comparison, because width determines how an insertable product feels far more than length does. So Surf is the more structured and fuller of the two, while Real is the slimmer and smoother.

Fun Factory does not publish battery capacity or operating time for Stronic Real on the product page, and the model’s quick guide has no readable text layer. That means you can’t compare Reals battery to Surfs 900 mAh without guessing. If you want that comparison documented, Surf is the only one of the two that gives you the information you need.

Compared with Stronic Wave and Stronic Smooth — 170 SEK cheaper, respectively larger

Stronic Wave costs from 336 SEK, i.e. 170 SEK less than Surf. It measures 211 × 41 × 41 millimeters and weighs 276 grams, has ten shock programs, IPX7, and USB-C. So Wave is 6 millimeters longer but 6 millimeters narrower than Surf, and it’s the cheapest way into Stronic technology among the five models — provided that the store that has the price also has the item in stock.

Stronic Smooth costs from 524 SEK and is the largest: 216 × 45 × 38 millimeters and 328 grams. The name is descriptive — it’s smooth, while Surf has the most pronounced structure in the lineup. When you choose between them, in practice you’re choosing between structure and a smooth surface, not between different technology.

What’s common across the entire family is worth stating clearly: all five are IPX7, all charge via USB-C, all are made of ABS, PC, and silicone, none of them have app control, and none of them have vibration beyond the shock movement. If you’re looking for a product that both shocks and vibrates, none of these are the answer.

Price range: 506 to 695 SEK, and four stores with stock

Five Swedish stores sell the item with EAN 4255821802401. The cheapest is Joyland at 506 SEK, and the most expensive is Blush Me and SexleksakerOutlet at 695 SEK each. That’s 189 SEK or a 37 percent difference for the exact same item number, same color, and same packaging.

The stock situation is unusually good in this case. Four of the five stores had the product in stock at the price check — Joyland at 506 SEK, Vuxen at 524 SEK, and Blush Me and SexleksakerOutlet at 695 SEK. Sexonic listed it at 555 SEK but without stock. That means the difference between the cheapest and the second-cheapest available is 18 SEK, while the jump up to the two most expensive is just under 190 SEK.

Two things belong in the price range. Shipping costs differ noticeably: Joyland lists 69 SEK in shipping in its product flow and Sexonic 98 SEK, while Blush Me and SexleksakerOutlet list zero. With shipping included, Joyland is still the cheapest, but the margin shrinks. And since the charging cable isn’t included, the person who doesn’t have a USB-C cable at home needs to add that cost regardless of store — it’s not an extra perk, but a prerequisite for the product to work.

For reference, the manufacturer sells the model itself in its own shop for 64.95 euros. The prices in the table above are updated when the stores’ product feeds are updated, but always check the final price at checkout.

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

It’s a good fit if you specifically want a thrusting movement rather than vibration. This isn’t a difference in degree—it’s a difference in type. And if you already know that vibration doesn’t do much for you, you have very little else to choose from. It’s for you if you want a wider, clearly structured product—47 millimeters is the widest measurement among Fun Factory’s five pulsators. It’s for you if you want to be able to rinse off the entire product under running water, and for you who prefer a regular USB-C cable over a product-specific charger.

It’s not for you if you need long runtime. About 40 minutes per charge, with roughly three hours of charging time, is short and makes the product unsuitable for long sessions without a charging break. It’s not for you if you want the smallest possible product—205 millimeters and 294 grams are substantial, and Stronic Dive is both shorter and 62 grams lighter. It’s not for you if you want app control or vibration as a complement, because the specification doesn’t include either of it. And it’s not for you if you require a published sound level or a published stroke length before buying, since Fun Factory publishes neither.

One final thing belongs in the decision, and it applies to all pulsators: a product that moves on its own has more mechanically moving parts than a product that only vibrates. It’s one of the few categories where a long manufacturer’s warranty actually means something—and that’s where Fun Factory’s commitment is unusually strong. Which leads to the next section, because it needs a clarification.

Warranty, complaints, and the right of withdrawal

Fun Factory’s packaging carries the symbol 25 YEAR GUARANTEE, meaning a 25-year warranty. It’s the longest commitment in this entire product category and it’s printed on the manufacturer’s own cardboard box.

Read the terms before you count on it. The manufacturer’s FAQ ties the 25-year promise to products bought directly from Fun Factory—either in the manufacturer’s own web shop or in their previous own stores—upon presentation of proof of purchase. Elsewhere in the same FAQ, however, the manufacturer states 24 months for Fun Factory products in general. The two pieces of information sit side by side on the same page on the manufacturer’s site, and Fun Factory does not clarify how they relate to each other. If you shop at any of the five Swedish stores above, the same FAQ additionally states that the complaint must be directed to the seller, not to the manufacturer—Fun Factory does not handle complaints for products that were not bought directly from them.

An easy-to-miss exception: the manufacturer states that the warranty entitlement can be lost if the product has been used together with oils or creams. Coconut oil, sun oil, sun cream, lip balm, essential oils, and cooking oils are all listed by name. Use a water-based lubricant—and only a water-based one.

What always applies, however, is your statutory rights, and they are independent of what the manufacturer promises. Under konsumentköplagen (the Swedish Consumer Sales Act), you have a three-year right to make a complaint regarding defects in the goods. For distance purchases, you also have a right of withdrawal for fourteen days under lagen om distansavtal och avtal utanför affärslokaler (the Swedish Distance Contracts and Off-Premises Contracts Act). Be aware that, in practice, the right of withdrawal is limited for hygiene items that have been taken out of a sealed package — however, the right to make a complaint for defects always applies. If you have questions about what applies in your case, Konsumentverket will guide you via Hallå konsument.

Frequently asked questions about Fun Factory Stronic Surf

What is the difference between a pulsator and a vibrator?
A vibrator shakes in place using a rotating weight—high frequency, very little movement. A pulsator like the Stronic Surf moves the entire shaft back and forth in the longitudinal direction, meaning it’s slower but with much more movement. Fun Factory states directly on the product page that the Stronic Surf is neither a vibrator nor a dildo, but a pulsator that thrusts on its own. The consequence is visible in the battery data: moving 294 grams back and forth costs more energy than vibrating the same mass, which explains why the runtime is stated as approximately 40 minutes despite a battery of 900 mAh.
How many settings does the Fun Factory Stronic Surf have?
Ten thrust programs. The manufacturer’s quick guide specifies the breakdown as seven speed levels plus three patterns, and Joyland, Vuxen, and Blush Me list the same split in their product texts. You switch between them using the plus and minus buttons on the handle, from 1 to 10 and back. There is no separate button for choosing patterns. For comparison, the manufacturer lists four speed levels plus four patterns for the Stronic Dive, meaning eight programs.
How is the Fun Factory Stronic Surf charged, and is the cable included?
Via USB-C, and no—the cable is not included. The quick guide’s charging section explicitly states that a USB-C charging cable is not included, and three of the Swedish stores repeat this, adding that any standard USB-C cable works. The port sits in the bottom of the handle behind a red sealing flap in rubber, which is what makes the IPX7 rating possible. Charging time is stated as about 3 hours, the charging voltage as 5 volts, and the maximum charging current as 500 mA—so a more powerful fast charger makes no difference. Note that Joyland, in its product text, writes that the pulsator is charged with Fun Factory’s magnetic USB cable; this is contradicted by the manufacturer and by three other stores, and it likely refers to an earlier generation.
How long does the battery last in the Stronic Surf?
The manufacturer states an operating time of about 40 minutes on a lithium-ion battery of 900 mAh and 3.7 volts, and Joyland lists the same figure in its store text. The charging time is about 3 hours, meaning roughly 4.5 minutes of charging per minute of use. That’s short compared with vibrators in the same price range, but it’s typical for pulsators: Fun Factory’s own Stronic Dive has 500 mAh and is stated to last about 30 minutes, which gives roughly the same ratio between capacity and operating time.
Is the Fun Factory Stronic Surf waterproof?
Yes, it is rated IPX7 according to the manufacturer’s product page, quick guide, and packaging symbol. According to the standard IEC 60529, that means the product has been tested for submersion in water to a depth of one meter for 30 minutes, and Fun Factory’s FAQ states that all rechargeable products from the brand are completely waterproof. This assumes that the sealing tab over the USB-C port is in place — an enclosure rating applies to the product when closed. Storage temperature is −5 to +60 degrees, which rules out boiling and a dishwasher.
How big is Stronic Surf, and how much fits in?
The manufacturer states 205 × 47 × 38 millimeters and 294 grams. The width of 47 millimeters makes it the widest of Fun Factory’s five pulsators — Stronic Real is 40 millimeters and Stronic Wave is 41 millimeters. Insertion length is not published by the manufacturer; the retailer Joyland states a penetrating length of 13.5 centimeters and a diameter of 4.5 centimeters. Adult and Blush Me state the total length as 20 centimeters, meaning the manufacturer’s 205 millimeters is rounded.
How quiet is Fun Factory Stronic Surf in decibels?
The manufacturer does not publish any decibel value, either on the product page, in the quick guide, or on the packaging, and none of the five Swedish stores lists any measured value either. Joyland writes that the pulsator works surprisingly quietly, but that’s a store’s wording without a figure behind it. Purely in principle, a pulsator has a reversal point at each end of the stroke that a rotating vibrator motor lacks, while the frequency is much lower — what the sum becomes can’t be calculated from the specification.
What does Fun Factory’s 25-year warranty cover if I buy in Sweden?
The packaging bears the symbol 25 YEAR GUARANTEE, but the condition needs to be read. The manufacturer’s FAQ links the 25-year promise to products purchased directly from Fun Factory — in their own web shop or in their previous own stores — with proof of purchase, and it states in another place on the same page 24 months for Fun Factory products generally. If you buy from a Swedish retailer, the claim must also, according to the same FAQ, be directed to the seller, not the manufacturer. Regardless of the warranty, you have a right to make a complaint for three years under the konsumentköplagen and a right of withdrawal within fourteen days for distance purchases, with the practical exception that the withdrawal right is limited for sealed hygiene items that have been opened. Also note that the manufacturer states that the warranty right can be lost if the product has been used with oils or creams.

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.
