Fun Factory Darling Devil: review

Fun Factory Darling Devil at a glance — this is what you get

Fun Factory Darling Devil is a rabbit vibrator, meaning it is a product built to stimulate the G-spot and the clitoris at the same time with two separate parts on the same body. The manufacturer describes it as a curved shaft for targeted G-spot stimulation, with a ridged structure along the shaft, an integrated clitoral stimulator on the side, and a pair of devil horns at the tip. It is the horns that gave the model its name, and they do not sit on the clitoral part, but at the very top of the insertable part.

According to Fun Factory, the specification looks like this: the total length is 20.5 centimeters, the diameter varies between 2.4 and 3.8 centimeters, the weight is 205 grams, the material is listed as silicone and ABS plastic, the protection rating is IPX7, and the product is powered by two AAA batteries that are not included. The number of vibration programs is ten, split across four speeds and six rhythms. The manufacturer’s article number for the burgundy variant is FF000996WR01.

This review is exclusively about the burgundy variant with EAN 4255821801244. Fun Factory sells Darling Devil in two colors — Burgundy, which in Sweden is marketed as Wine Red, and Black with EAN 4255821801268. Functionally, they are identical, but the numbers are different, and several stores mix the colors on the same page. In Sweden, the item is sold by five stores at prices between 297 and 539 SEK, and four of them had it in stock at the price check on July 29, 2026.

What most sets this product apart from the rest of the category is not the shape but the mode of operation. Nearly everything else in the same price range is rechargeable. Darling Devil is battery-powered, and that is the single most important thing to understand before deciding—because it affects both what it costs to own, how it behaves over time, and what happens on the day it stops working.

What a rabbit vibrator is—and what the horns actually do

A rabbit vibrator has two stimulating parts that are fixed into the same body and share a motor. One part is inserted, while the other sits on the outside against the clitoris. The point is that the distance between them is fixed, which means both surfaces end up in the right place at the same time—as long as your anatomy matches the construction’s measurements. That’s also the fundamental weakness: if the distance doesn’t fit, no setting in the world helps, because it isn’t possible to adjust where the clitoris part sits in relation to the shaft.

Fun Factory states that the Darling Devil has a bent shaft. The bend in the shaft is what makes the pressure from the tip point forward toward the front vaginal wall instead of straight in, and that’s the entire technical idea behind a G-spot product. The ridged structure along the shaft, according to the manufacturer, is intended for extra stimulation—in other words, it creates a sensation during movement that a completely smooth surface doesn’t provide.

The horns are the detail that sets the model apart from a standard rabbit. The manufacturer describes them as a playful shaping intended for intense internal stimulation, and in the manufacturer’s own product images you can see that they sit as two small upward-pointing tips on top of the shaft. In practice, that means the tip isn’t rounded and smooth, but has two point-shaped sections that create a more concentrated pressure than an even dome. What can be established is that this shape increases variation in the contact area—of course, the manufacturer doesn’t publish a number for how much that shows.

Darling Devil, Ocean, Amorino, or Miss Bi— which Fun Factory rabbit is which?

Fun Factory has four products in its range that the brand itself classifies as rabbit vibrators, and they’re often mixed up in Swedish shops because they look closely related. The differences are nonetheless significant, and they mostly come down to power.

• Darling Devil — the model this text is about. 20.5 centimeters, 205 grams, battery-powered with 2 × AAA, ten programs, IPX7, list price 46.95 euros from the manufacturer.
• Ocean — the smaller battery-powered rabbit. 140 × 50 × 38 millimeters and 116 grams, the same material combination silicone and ABS plastic, the same IPX7 and the same battery type 2 × AAA. List price 38.95 euros.
• Amorino — rechargeable rabbit with a charging indicator. 17.7 centimeters, diameter 2.1–3.2 centimeters, 147 grams, six speeds and six rhythms, touch lock, run time 1–4 hours and charging time 8 hours on the first charge. List price 53.95 euros.
• Miss Bi — the biggest and heaviest. 173 × 76 × 38 millimeters, 230 grams, silicone, ABS plastic, and polycarbonate, IPX7 and rechargeable battery. List price 53.95 euros.

The conclusion of this comparison is simple, and it’s worth taking with you: within Fun Factory’s own range, the step from battery-powered to rechargeable costs seven euros on the manufacturer’s own price list. It’s a small amount compared to what a rechargeable battery means for operating costs, and it’s that comparison that determines whether Darling Devil is the right purchase or not.

Materials and build quality: silicone on the shaft, ABS in the handle

The material issue is the only property of an intimate product that can’t be compensated for with experience or care, and it determines whether the product is still hygienic after five years. Fun Factory lists two materials for Darling Devil: silicone and ABS plastic. The manufacturer’s own product images show where the boundary lies: the entire molded portion with shaft, horns, and clitoral stimulator is silicone, while the lower third that forms the handle and battery compartment is a glossy, metallized plastic part with three buttons.

What medical silicone means in practice

Silicone is a non-porous material. A non-porous surface can be cleaned, because there are no microscopic cavities where residue can remain. It’s the single most important property of a material that’s meant to lie against mucous membrane, and that’s why the material declaration carries more weight than almost any other line in a specification.

Fun Factory is unusually clear in its FAQ. It states that the brand’s products consist of 100 percent medical silicone, that the material is hypoallergenic, non-porous, vegan, and halal, and that the battery housing and control part are made from body-friendly thermoplastic. It’s a much more specific wording than the common store phrase “kroppssäkert material,” and at the same time it confirms the breakdown: the plug-in part is silicone, and the part you hold is plastic.

This breakdown has a practical consequence that’s easy to miss. The seam between the silicone part and the plastic handle is a physical joint, and a joint is always the point where dirt collects and where water can get in. It’s also where a product of this type normally breaks first. If you want silicone across the whole body, it isn’t available in this model — and neither is it in Ocean or Miss Bi either, both of which are listed with the same material combination.

Phthalates, BPA, and plasticizers — why the material declaration matters

Phthalates are a group of plasticizers used to make plastic — above all softened PVC — flexible. Kemikalieinspektionen describes them as substances that can affect the endocrine system and make reproduction more difficult, and several of them are therefore restricted or banned within the EU in a large number of products. This specific product category is a recurring subject of supervision because it contains softened plastic in contact with skin.

Fun Factory explicitly states in its FAQ that all products are free from softeners, BPA, and phthalates. The retailer Joyland also lists its own line in its specification table, where the product is stated to be phthalate-free. Two independent pieces of information pointing in the same direction are better than one, even if the manufacturer’s own declaration is the one that carries the most weight.

There is a technical reason why silicone as a material specification on its own is a better piece of information than almost any other detail in a product specification: silicone does not require phthalate softeners to become soft. The softness comes from the polymer’s own structure. That is different from labels such as "TPE" or "jelly rubber", which say nothing at all about which softeners are included.

Dimensions and weight: 20,5 centimeters, Ø 2,4–3,8 centimeters, and 205 grams

Fun Factory lists the total length as 20,5 centimeters and the diameter as 2,4–3,8 centimeters. Stating the diameter as an interval and not as a value is, in itself, informative: the shaft is therefore not equally wide all the way, but tapers toward the tip and is widest in the lower part of the silicone section. The weight is given as 205 grams.

Compared with Fun Factory’s own alternatives, Darling Devil is the longest of the battery-powered models. Ocean measures 140 millimeters and weighs 116 grams, which is therefore just under 60 percent of Darling Devil’s weight. Amorino is 17,7 centimeters and 147 grams. Going outside the brand, Lelo Ina Wave 2 is almost identical in size: 200 × 65 × 45 millimeters and 176 grams. What can be established is that Darling Devil sits in the middle of the full-size segment—it is not a compact model, but it is also not anywhere near the heaviest.

The weight of 205 grams deserves a footnote. The product is sold without batteries, and two AAA batteries normally weigh around 20–25 grams together depending on chemistry. The manufacturer does not specify whether the 205 grams refers to the product with or without batteries. Fun Factory also does not publish a separate figure for shipping weight, even though the variant table in the shop data on the manufacturer’s own site states 207 grams—a difference of two grams that has no practical significance, but shows that the two pieces of information are not taken from the same measurement.

The insert depth that the manufacturer does not publish

Here there is a hole in the manufacturer’s specification that is worth pointing out, because it is exactly that figure that determines whether a rabbit vibrator fits a certain body. Fun Factory does not publish an insertable length for Darling Devil—either on the product page or in the specification table. The total length of 20,5 centimeters says nothing about how much of it actually goes in, because the clitoral stimulator sits a bit up on the shaft and stops the movement there.

The stores fill in the gap, but they’re not in agreement. Both retailers Joyland and Vuxen state a 10-centimeter insertable length. Blush Me states 9.00 centimeters. The difference of one centimeter isn’t dramatic, but it illustrates the problem: none of the figures come from the manufacturer, and you can’t verify them against anything. Count on the 9–10 centimeter range and treat it as a guideline, not as a measurement.

For the sake of comparison, Lelo publishes that figure for the Ina Wave 2: 110 millimeters insertable length out of a total of 200 millimeters, i.e. 55 percent of the product. The fact that a competitor in the same size class reports the same information shows that it isn’t technically impossible to measure—it’s a choice not to publish it.

Ten vibration programs and three buttons

The interface on the Darling Devil consists of three buttons placed in a row on the front of the handle. The manufacturer’s own product images show them clearly: a minus button at the top, a red button in the middle labeled FUN, and a plus button at the bottom. This is Fun Factory’s standard interface, and it appears on several models in the lineup.

The specification states a total of ten vibration programs, distributed across four speeds and six vibration rhythms. The same breakdown appears in the manufacturer’s function graphic—on the packaging, where the symbol indicates "10 MODES"—and on all four Swedish stores that publish a specification. It’s uncommon for a numeric detail to match all the way from the manufacturer’s side to the store listings, and here it does.

Four speeds and six rhythms—what’s the difference?

The split between speeds and rhythms isn’t just cosmetic, and it’s worth understanding before you buy. A speed is a constant vibration at a given intensity: the motor runs evenly and the sound is stable. A rhythm is a pattern where the intensity varies over time—pulses, rising waves, interruptions. Four speeds therefore means four levels of constant vibration, and six rhythms means six pre-programmed patterns that you can’t change the intensity on independently.

In practice, that means the stepless part of the product is four steps, not ten. The rhythms are fixed programs. That’s an important difference compared with how the “10” figure is often presented in store texts, where ten settings sound like ten different intensities you can choose between. Compare with Fun Factory’s own Amorino, which is listed with six speeds and six rhythms—in that case, the stepless part of the scale is therefore 50 percent longer.

The Lelo Ina Wave 2 is listed with a total of twelve settings without showing the breakdown between speed and patterns in the same way, which means the twelve and the ten aren’t directly comparable. This is a recurring problem in this category: the number of settings is the figure that’s marketed most strongly and that means the least, because no manufacturer defines it the same way.

The buttons: minus, FUN, and plus

The layout across three buttons follows a simple logic. Plus and minus step through the intensity, and the FUN button switches between programs. The fact that strength and program have separate controls means you can raise and lower them without the program changing, which is the difference versus one-button products where every press changes everything at once.

Fun Factory does not publish an operating manual for Darling Devil in its download section, and the product page does not describe the length of the button presses, whether there is a travel lock for the touch keys, or whether the product remembers the last setting. It’s a genuine gap: the manufacturer expressly lists a touch-key travel lock for Amorino in that model’s specification table, but makes no corresponding note for Darling Devil. In other words, what applies is something you’ll have to read up on from the leaflet that comes in the package.

One thing you can, however, confirm directly from the manufacturer’s FAQ—one that’s also practically useful—is this: if a battery-powered Fun Factory product starts acting up in the same second that you close the battery compartment, then it isn’t broken—the batteries are fitted the wrong way around. It’s one of the few troubleshooting instructions the manufacturer actually publishes for its battery models.

Battery operation: two AAA batteries and what that means

Darling Devil is powered by two AAA batteries that are not included in the delivery. It’s stated on the manufacturer’s product page, in the function graphic, in the symbol row on the package, and by all Swedish retailers that publish the information. Joyland also specifies the battery type as AAA (LR3), meaning common alkaline stick batteries.

How is Fun Factory Darling Devil charged?

It doesn’t. There is no charging connector, no cable, and no charging indicator—the product instead uses battery replacement. It’s a trade-off with two clear sides.

The advantage is that you never have to wait. There’s no charging time, no risk that the product is out of power when you need it, and no battery that degrades with the number of charging cycles. There’s also no proprietary charging cable you could lose—compared with models where a magnetic charging cable is product-specific and can’t be replaced with a regular USB cable. A couple of AAA batteries are available in every grocery store in Sweden.

The downside is the ongoing cost and environmental impact, and it’s not negligible. Fun Factory also explicitly advises in its FAQ against using rechargeable batteries in its battery-powered products and states that standard 1.5-volt batteries should be used. That means the obvious solution—rechargeable NiMH cells—is, according to the manufacturer, not an option, since rechargeable AAA cells are 1.2 volts and therefore provide lower voltage to the motor. With battery replacement every other week, that works out to around thirty disposable cells per year per product.

The manufacturer also provides a storage instruction that’s easy to overlook and that directly affects the service life: remove the batteries after use and leave the battery compartment open. The reason is that alkaline batteries leak when they’re fully discharged inside a closed compartment, and a leak in the battery compartment is, in practice, the end of the product because the contacts corrode.

Runtime that is not published

Fun Factory does not publish any operating time for Darling Devil—not in hours, in minutes, or as a range. None of the five Swedish stores publishes it either. That means the most-requested piece of information about a battery-powered product is completely missing from the source, and that gap is something you should be aware of.

That said, a comparison is still possible because the manufacturer publishes the figure for its rechargeable models. Amorino is listed as 1–4 hours of operating time and 8 hours of charging time for the first charge. Lelo states up to 2 hours for Ina Wave 2 on a lithium-ion battery with 520 mAh and 3.7 volts, with a 2-hour charging time. That gives an order of magnitude for what the category normally delivers, but it doesn’t say anything about what two alkaline AAA cells are enough for in this specific motor—and no one should claim to know that figure without the manufacturer’s information.

What you can, however, establish in principle is that a battery-powered product behaves differently toward the end of the battery’s life than a rechargeable one. An alkaline battery loses voltage gradually during discharge, which normally shows up as the vibration becoming weaker before it finally runs out. A lithium-ion cell keeps the voltage more even and drops off more sharply at the end. Which behavior you prefer is a matter of taste, but it’s a real difference in how the product feels over the course of use.

Water resistance: IPX7, with a caveat

Fun Factory lists Darling Devil as waterproof according to IPX7. The information is included both in the product description and as a symbol on the packaging, and it’s repeated by the stores Blush Me and SexleksakerOutlet, both of which print IPX7 directly. Joyland lists "Waterproof: Yes" without any class rating.

The rating comes from the international standard IEC 60529, which defines enclosure ratings 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. So it’s not splash protection but actual water resistance, which means the entire product can be rinsed under running water.

IPX7 for the battery compartment cover — the caveat that matters

Here lies the most important reservation in the entire specification, and it comes from the manufacturer itself. Fun Factory states in its FAQ that the rechargeable products are 100 percent waterproof, while the battery-powered products are waterproof as long as the battery compartment is properly closed. This is conditional waterproofing, not unconditional.

The difference is practically significant. On a rechargeable product with magnetic charging, there is no opening at all in the housing—which is why it is sealed regardless of what the user does. On a battery model, the watertightness depends on a seal sitting correctly and the lid being completely closed, every time. A not-fully-closed flap means that water gets into the battery compartment, where both contacts and electronics are located. So this is not a theoretical caveat but a concrete handling requirement.

Therefore check the flap before taking the product into a shower or bathtub, and avoid opening the battery compartment with wet hands. These are simple habits, but they are the entire difference between whether the IPX7 rating applies and whether it does not.

Cleaning, lubricant, and storage

Fun Factory’s own instructions are brief and clear. Clean the product with warm water and mild soap, both before and after each use, and also before the very first time you use it. The manufacturer recommends its own cleaning agent for silicone products, but it also states that water and mild soap are enough.

On the question of lubricant, the message is unambiguous: never use a silicone-based lubricant on a silicone product, because it cannot be fully removed and makes the product unhygienic despite careful cleaning. Use a water-based lubricant. The retailer Joyland gives the same recommendation in its own specification table.

The manufacturer goes even further than that and ties the issue to the warranty. In its FAQ, Fun Factory explicitly warns that oils and creams—suntan oil and suntan cream, lip balm, essential oils, coconut oil, and all types of cooking oils—can cause irreparable damage to the control part and to the entire product, and that you risk losing your guarantee right if you use them. This is an unusually sharp wording, and it should be read literally.

The advice about the batteries also belongs here: remove them between uses and leave the flap open during storage. Store the product dry and separately from other silicone products, because different silicone blends can react with each other during prolonged contact.

Sound level: what is published and what is not

Fun Factory does not publish any measured decibel value for Darling Devil, either on the product page, in the specification table, or on the packaging. The manufacturer makes no sound claim at all about this particular model.

The only information found in the sources is a store listing: Joyland states in its specification table “Sound level: Low.” It is a qualitative assessment without measurement and without a measurement method, and it should not be read as anything else. Websites that list an exact number of decibels for this product either show their own measurement or a value without a source.

What can be established on a technical basis is that a battery-powered product with an eccentric motor and a plastic body typically sounds louder than a rechargeable silicone-clad model, because a hard plastic housing transmits and amplifies motor noise better than a soft material does. It is a general property of the design and not an assertion about just Darling Devil. A practical tip that applies regardless of model: place the product on a soft surface during use instead of on a hard tabletop, which works as a resonance box.

Darling Devil compared with the alternatives

Three comparisons are relevant: against the smaller battery-powered rabbit in the same range, against the rechargeable one in the same range, and against a same-size competitor from another brand. All information below comes from the respective manufacturers’ own specifications, and all Swedish prices come from the shops’ product feeds on July 29, 2026.

Against Fun Factory Ocean — same technology, smaller body

Ocean is Fun Factory’s second battery-powered rabbit, and it is technically very close to Darling Devil. Both are listed with silicone and ABS plastic, both have IPX7, and both run on two AAA batteries. The difference is size: Ocean measures 140 × 50 × 38 millimeters and weighs 116 grams, compared with Darling Devil’s 20.5 centimeters and 205 grams. So Ocean is both shorter and almost half as heavy.

In the manufacturer’s own price list, Ocean costs 38.95 euro, versus Darling Devil’s 46.95 euro. So what you pay those eight euros for is essentially size, the ribbed structure, and the horn shape — not the technology, because the operating mode, waterproofing class, and material combination are the same. If you want a battery-powered Fun Factory rabbit in a smaller format, Ocean is the direct way there, and it is also the cheaper option.

What’s the difference between Darling Devil and Fun Factory Amorino?

Amorino is the comparison that matters most, because it isolates exactly one variable: the power supply. Amorino is rechargeable and has a charging indicator. It is listed with six speeds and six vibration patterns, compared with Darling Devil’s four and six, and it has a touch lock, which Fun Factory does not state for Darling Devil. The runtime is published — 1 to 4 hours — and the charging time is listed as 8 hours for the first charge. In the package you get the product, the charging cable without a USB adapter, and a booklet with instructions for use.

The dimensions also differ: Amorino is 17.7 centimeters versus 20.5, the diameter is 2.1–3.2 centimeters versus 2.4–3.8, and the weight is 147 grams versus 205. So Amorino is consistently a narrower and lighter product.

The price difference from the manufacturer is 7 euros — 53.95 versus 46.95. For that money, you get a rechargeable battery, two extra speed levels, a published runtime range, a tangent lock, and an instruction manual in the package. What speaks in favor of Darling Devil in this comparison is that it is larger, that it has the horn shape and the ridged structure, and that it never needs to be charged. It’s a slim margin, and anyone who doesn’t specifically want battery-powered operation should consider Amorino first.

Against the Lelo Ina Wave 2 — almost the same size, completely different specifications

The Lelo Ina Wave 2 is interesting precisely because it is almost exactly the same size: 200 × 65 × 45 millimeters and 176 grams, versus Darling Devil’s 205-millimeter length and 205 grams. That’s where the similarities end.

Lelo publishes insertable length (110 millimeters), diameter (37.09 millimeters), battery capacity (520 mAh at 3.7 volts), charging time (2 hours), runtime (up to 2 hours), number of modes (twelve), automatic shut-off after 20 minutes of inactivity, the material (body-friendly silicone and ABS plastic), and the warranty terms: a two-year manufacturer warranty plus a ten-year quality warranty. Fun Factory publishes none of the first four of those for Darling Devil.

The differences that actually matter: Ina Wave 2 is rechargeable and has a published runtime, a published battery capacity, and a published insertable length. Darling Devil is cheaper, requires no charging, and costs nothing to have sitting there. If you choose based on the stated data, Lelo wins without competition. If you choose based on the purchase price and on never having to think about a charging cable, Darling Devil wins.

When the shops contradict each other — and when they contradict the manufacturer

This product is a textbook example of why store details shouldn’t be treated as specifications. Four of the five Swedish stores publish their own numerical figures, and they don’t match.

• Total length: the manufacturer states 20.5 centimeters. Joyland states 20.5. Vuxen and Blush Me state 20.
• Diameter: the manufacturer states an interval, 2.4–3.8 centimeters. Vuxen states 3.8 — meaning the upper value of the interval. Blush Me states 3.70 as the largest diameter. Joyland states 4 centimeters, which is outside the manufacturer’s stated range.
• Material: the manufacturer states silicone and ABS plastic. Joyland states the same. Blush Me only writes “high-quality silicone,” and SexleksakerOutlet only writes “soft, body-safe silicone” — both omit the plastic part.
• Water resistance: the manufacturer states IPX7. Blush Me and SexleksakerOutlet write IPX7. Joyland writes “Yes.” Adults say “Waterproof: No” — which directly contradicts the manufacturer.

The rule is simple: when a shop goes against the manufacturer, the manufacturer wins. So the product is classified as IPX7 according to Fun Factory, regardless of what the line at Vuxen says, and the material is silicone and ABS plastic regardless of the fact that two shops only mention the silicone. But the deviations are worth knowing, because they explain why different price-comparison sites provide different values for the same article number — they have taken the figure from different shop data feeds instead of from the manufacturer.

Price range: 297 to 539 SEK and four shops with stock

Five Swedish shops sell the item with EAN 4255821801244. The cheapest is Joyland at 297 SEK, the most expensive is Blush Me and SexleksakerOutlet at 539 SEK each. That’s 242 SEK, or just over 81 percent difference for exactly the same article number, the same color, and the same packaging.

The stock situation is unusually favorable here. Four of the five shops had the product in stock at the price check, and the only one that didn’t — Sexonic at 403 SEK — was in the middle of the price range. That means the cheapest shop is actually the cheapest available, which isn’t always the case. The second-cheapest in stock is Vuxen at 404 SEK, i.e. 107 SEK more than Joyland.

Set the numbers against the manufacturer’s own list price to see how big the spread really is: Fun Factory sells the Darling Devil for 46.95 euros in its own store. So the Swedish floor price of 297 SEK is clearly below the list, while the ceiling price of 539 SEK is clearly above it. The price spread isn’t because any shop sells a different variant — all five list the item under EAN 4255821801244 or under their own article number that is linked to that specific burgundy Darling Devil.

The prices in the table above are updated when the shops’ product feeds are updated, but always check the final price at checkout. Shipping costs are added by most shops below a certain order value, and in this price range all five shops are below the threshold for free shipping at most of them — which can eat up some of the 107 kronor between the cheapest and the second-cheapest option.

Also factor in the batteries. The product is delivered without them, so you need to add a pack of AAA batteries directly to the purchase price, and then there’s an ongoing cost as long as the product is used. It’s the only product type in the category where the purchase price isn’t the entire cost.

Who manufactures Fun Factory today?

A note that belongs in a source-based review: Fun Factory has long been known as a German brand with production in Bremen, and that picture remains in much of the store copy. On the product page for Darling Devil, it is today stated under the heading "Hersteller" that the manufacturer and responsible person in the EU’s sense is Triple A Import GmbH, Am Lenkwerk 3, 33609 Bielefeld. That is the legally applicable responsibility for this article.

What that means for you as a buyer is limited but not zero: if a complaint goes past the store, it ends up there, and that is the address listed as responsible for product safety. That a store text describes the product as made in Germany is not a claim the manufacturer makes about this exact model on its own product page, and you shouldn’t place much weight on that in your purchase decision.

Who is Fun Factory Darling Devil for—and who isn’t it for?

It fits you if you want a full-size rabbit vibrator without spending premium money, and if you see battery operation as an advantage rather than a drawback. There’s a real group where that applies: the one who uses the product rarely and has therefore grown tired of always having to find it dead, the one who travels and doesn’t want yet another charging cable, and the one who wants a product that keeps working even after three years in a drawer—which a built-in lithium-ion battery rarely does.

The material also speaks in its favor: silicone on the entire body-contact part, a manufacturer that declares freedom from plasticizers, BPA, and phthalates, and an IPX7 rating that means the whole product can be rinsed off. In the 297 SEK price range, that isn’t a given, and it’s the strongest part of the specification.

It’s not for you if you want to know exactly what you’re buying before you pay. The manufacturer does not publish the insertable length, operating time, sound level, or delivery contents for this model, and three of the four can be obtained from competitors in the same size class. It doesn’t fit you if you want a stepless and long intensity scale—four speeds are the adjustable part; the rest are fixed programs. It doesn’t fit you if you don’t want ongoing battery costs, and it doesn’t fit you if you want guaranteed water resistance, because the manufacturer’s IPX7 for the battery models applies provided that the cover is closed properly.

One more thing belongs in the decision. The difference compared to Fun Factory’s own rechargeable Amorino is seven euros on the manufacturer’s price list. If you don’t specifically want battery operation, that’s the comparison you should make first—and if you make it and still choose Darling Devil, then you’ve made a conscious choice instead of an assumption.

Warranty, complaints, and right of withdrawal

Fun Factory offers a 24-month warranty on all products with proof of purchase, and the same information is listed as a symbol on Darling Devils packaging: "2 YEAR GUARANTEE". The manufacturer is clear that a receipt, proof of payment, or a bank statement is required — without proof of purchase, it is not possible to have the case reviewed.

There are two limitations you should know about before you count on the warranty. The first is the oil warning: Fun Factory states explicitly that using oils and creams can cause irreparable damage and that you risk losing your right to claim under the warranty. The second is the place of purchase — if you bought the product from a retailer, the manufacturer asks you to contact that retailer first with the complaint, not Fun Factory directly.

What always applies, however, are your statutory rights, and they are stronger than the manufacturer’s promise. Under konsumentköplagen, you have a three-year right to complain about defects in the goods, i.e. one year longer than Fun Factory’s warranty. For distance purchases, you also have a right of withdrawal for fourteen days under the Act on distance contracts and off-premises contracts (lagen om distansavtal och avtal utanför affärslokaler). Be aware that in practice, the right of withdrawal is limited for hygiene products that have been removed from a sealed package — however, the right to complain about defects always applies. If you have questions about what applies in your case, Konsumentverket guides you via Hallå konsument.
