Best budgetReview · App-controlled rabbit vibrator · Thrust technique
IntoYou’s app-controlled thrust vibrator reviewed against the manufacturer’s own specifications and pricing data from four Swedish stores. Three independent motors with ten settings each, ActiveJoy control without an account, 248 millimeters total length and three years of warranty — but without a published IPX rating, without weight, and with a battery figure that doesn’t add up with the stated operating time.
The cheapest way to get a real thrusting motion with app control. Three independent motors with ten modes each provide more combinations than the price tag suggests. ActiveJoy does not require an account or an email address, and a three-year warranty beats We-Vibes two. What you pay for is the documentation: no IPX rating, no weight, no manual, no shipping contents, and a capacity figure of 57 mAh that doesn’t match the stated operating time of 100 minutes.
IntoYou Ascen is an app-controlled rabbit vibrator from the manufacturer’s App Series, and it differs from most rabbit models in one easily overlooked point in store texts: it has three separate motors that, according to the manufacturer, can be used simultaneously or separately. The tip moves up and down at the same time as it sways, the shaft vibrates, and the small clitoral arm has its own vibration motor with a ball on top. The manufacturer specifies ten modes for each function, i.e. thirty modes total.
The rest of the specification looks like this. The manufacturer lists the dimensions as 24.8 × 3.5 centimeters, a 57 mAh battery, a 50-minute charging time, and an operating time of up to 100 minutes. Charging is done via a magnetic USB cable. The product is described as waterproof, and it’s controlled either with the buttons on the body or via the free ActiveJoy app—locally via Bluetooth up to ten meters, or globally via the internet. In Sweden, the item is sold by four stores at prices between 595 and 795 SEK, and all four had it in stock at the price check on September 12, 2026.
This review is about the item with EAN 8436615002986, which from the manufacturer carries the item number IN-298. The number is checked against the manufacturer’s own product feed, the distributor’s item sheet, and the app provider’s store, and it is the same number that all four Swedish stores list. Ascen is sold in a single color, red, according to both Joyland and Blush Me—so there’s no variant confusion to keep track of here, unlike most products in this price range.
Three English words appear in the product name and in all store texts, and they refer to three different things that are worth keeping separate before comparing the model with anything else.
In addition to the two, the shaft has ten of its own vibration modes. What can be established purely in terms of calculations is that three independent controls with ten steps each produce significantly more combinations than a scale with thirty settings would — and that's exactly the difference that store copy usually blurs when they write "30 settings" straight out. Compared with Fun Factory Bi Stronic Arc, which according to the manufacturer has eight pulse programs and six vibration programs, Ascen's specifications are more segmented but also more demanding to learn.
IntoYou is a European brand, and the manufacturer lists its own company details: Accessories Unlimited, S.L. in Callosa de Segura outside Alicante in Spain. Having the manufacturer write out a company name and a physical address is more unusual in this price range than you might think, and it matters in practice — that's the address a warranty case is sent to if the shop refers you onward.
App Series is the part of the range that is controlled via ActiveJoy. The manufacturer states that the products are CE-marked and manufactured in accordance with EU legislation, that all products have a three-year warranty, and that the materials are medical-grade silicone described as hypoallergenic and free from phthalates and other harmful substances. The manufacturer also explicitly states that all IntoYou toys have physical buttons and that the app is a supplement, not a requirement — which is a more important role than it looks like, and which comes up again further down.
The material is the only characteristic of an intimate product that can't be compensated for with habit or care, and it determines whether the product will still be hygienic a few years from now. There's also a discrepancy between the sources that is worth stating plainly, because it affects what you actually buy.
The manufacturer lists just one material on the product side: ultra-soft premium silicone. The distributor Servelec, which sells the same reference IN-298 with the same EAN, instead lists "premium silicone plus ABS". Among the Swedish shops, Joyland lists "ABS plastic, Silicone", while Blush Me and Vuxen only write silicone.
What to do with it? The manufacturer’s statement weighs heaviest when sources conflict, but here it’s not really a contradiction—it’s a matter of different levels of detail. The manufacturer’s own images show a gold-colored plate at the bottom of the handle where the buttons are, and a gold-colored ring around the clitoris arm. It is not silicone. The reasonable assumption is therefore that the contact surfaces—the tip, the shaft, the clitoris arm—are silicone, while the bottom plate and the decorative details are hard plastic. No material breakdown by part is published by the manufacturer, and it’s a documentation shortcoming rather than a defect in the product.
Why it matters: silicone is non-porous, and a non-porous surface can be cleaned because there are no microscopic cavities where residue can get trapped. ABS plastic is also non-porous, so both materials are, in themselves, hygienically acceptable. The problem with a mixed construction is instead the seams. Where silicone meets plastic there is a joint, and a joint is the only place on a product of this type where dirt can actually collect. On Ascen, there are at least two such joints: around the gold plate at the base and around the ring on the clitoris arm. They should be rinsed with special care.
Phthalates are a group of plasticizers used to make plastic—especially soft PVC—flexible. 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 in a large number of products. The category of intimate products is regularly the subject of supervision just because it contains soft plastic against skin and mucous membranes.
IntoYou states on its questions-and-answers page that all products are made of medical silicone that is hypoallergenic and free from phthalates and harmful substances. It is an unambiguous commitment, and it is also technically plausible: silicone does not require phthalate plasticizers to become soft, because the softness comes from the polymer’s own structure. It is exactly that difference that makes “silicone” as a material specification say more than terms like TPE or jelly rubber, which say nothing at all about which plasticizers are included.
Two reservations still belong here. The commitment applies to the range as a whole, not specifically Ascen—the manufacturer does not repeat it on the product page. And no test certificate, no material declaration per component, and no EU declaration of conformity is published. The manufacturer states that the products are CE-marked, but the actual declaration is not available openly. This is standard in the category and not unique to IntoYou, but it means that the material information rests on the manufacturer’s word and nothing more.
The manufacturer states the dimensions as 24.8 × 3.5 centimeters on the product page, and the same figures show up again in the manufacturer’s own dimension chart in millimeters: total height 248 mm and total width 35 mm. All Swedish retailers reproduce these two figures, and Vuxen and Joyland call the second figure diameter, while Blush Me writes "diameter max 3,50 cm".
Here’s a detail worth noting. The dimension diagram places the width arrow across the shaft, not across the product’s widest point including the protruding clitoral arm. What the 35 millimeters refer to — the shaft’s diameter or the product’s total width with the arm included — cannot be determined from the manufacturer’s material, because the label says "total width", while the arrow measures the shaft. Assume that the shaft’s diameter is around 35 millimeters and that the product is wider than that overall.
The insertable length is not published by the manufacturer. The retailer Joyland states 13 centimeters, which is the only information about insertable length that can be found and that should be read as a store detail, not as a manufacturer detail. The relationship between those figures is plausible in itself: a product that is 248 millimeters total, with a handle, a clitoral arm, and a movable part, leaves roughly that length remaining to insert.
For comparison, Lelo Ina Wave 2 measures, according to the manufacturer, 200 × 65 × 45 millimeters, with 110 millimeters insertable, and We-Vibe Nova 2 is stated as 217 × 85 × 39 millimeters. Fun Factory Bi Stronic Arc is 223 millimeters long with a diameter of 79 millimeters. So Ascen is the longest of the four, but that number should be read carefully: on a percussion vibrator, part of the length sits in the motor part and not in what’s inserted.
Weight is not published by the manufacturer, and none of the four Swedish retailers lists it either. It’s a real gap specifically for this product type, because a percussion motor needs a mechanism that weighs something—Fun Factory lists 336 grams for Bi Stronic Arc and Lelo 176 grams for Ina Wave 2, and the difference between the two figures says more about how a product feels in your hand than most other lines in a specification.
The interface on the product consists of buttons on the gold-colored plate at the base. The manufacturer’s product images show three button settings on the plate, which matches three independent functions that can be turned on and off separately. No button descriptions, no quick guide, and no online manual are published by the manufacturer—neither on the product page nor anywhere else on the manufacturer’s website. This is the biggest documentation gap for this model, and it clearly sets it apart from brands like Womanizer and Satisfyer, which publish the full manual openly.
What can be determined from the manufacturer’s own information, however, is that the product has physical buttons and works without an app. IntoYou expressly states that all products have physical controls and that the app is a complement and not a requirement, and ActiveJoy’s own product page formulates the same thing as “manual control or control via ActiveJoy.”
The manufacturer lists three scales: ten combined shock and swing modes at the tip, ten vibration modes in the body, and ten vibration modes in the clitoral stimulator. The manufacturer also states that the three functions are independent and can be used at the same time or separately.
In practice, this means two things. First, “30 modes” is a misleading summary — three scales of ten steps each that can be combined freely are a different thing than a single menu with thirty items, and anyone who compares by the number of programs is comparing incorrectly. Second, independent motors mean you can run the clitoral arm by itself without the shaft moving at all, which makes the product usable even for someone who doesn’t want an insert piece just then. It’s a more flexible design than a rabbit where a single program controls everything.
The counterargument is just as simple. Three scales means three things to set, on a product whose buttons are located at the very bottom of the handle and aren’t visible during use. The more controls there are, the longer it takes to find the right one — and without a published manual, there’s no way to read in advance which button does what. Expect the first few times to be spent learning the button order.
The app is the feature that the model name is based on, and it is also the area where the manufacturer documents the most. According to both IntoYou and ActiveJoy themselves, ActiveJoy is completely free, with no subscription and no hidden fees, and it’s available for both iOS and Android.
The manufacturer’s own overview image names six control modes: Automatic mode with built-in program selection, Touch mode where your finger controls the intensity by dragging across the screen, Music mode that synchronizes to music, Remote mode for remote control between two people, Audio mode where sound activates the toy, and Shake mode where you shake the phone. The product page adds motion control via the phone, as well as video mode and video chat mode for remote use.
The range is given by the manufacturer as up to ten meters in the local Bluetooth mode and unlimited via the internet in the remote mode. Ten meters is a normal Bluetooth range and should be read as a value measured in open air — a wall or two between the phone and the product will reduce it significantly, just like with any other Bluetooth device.
The privacy section deserves its own line, because it’s actually unusual. ActiveJoy states that the app does not require registration, an email address, or any personal information, and justifies it by saying that it doesn’t store information because it never asks for it. The Google Play listing for the app, which was last updated on September 3, 2026, states in the developer’s security declaration that no data is shared with third parties. For a product category where connected toys have, on several occasions, received criticism for data leaks, an app without an account is a real advantage—and it’s controllable, unlike most other marketing claims in the category.
Yes. The manufacturer states that all IntoYou products have physical buttons and that the app is a complement, and ActiveJoy describes the control as either manual or via the app. It’s a more important task than it sounds, because an app-controlled product whose app stops being maintained otherwise becomes unusable the day a phone operating system is updated. With physical buttons, the app is a feature you can lose without losing the product.
Which of the thirty modes that are possible to reach from the buttons, and which ones are only possible to reach via the app, the manufacturer does not publish. It’s a reasonable question to ask before buying, and the answer isn’t in the manufacturer’s materials. Based on experience, combination modes and custom patterns usually are in the app, while the basic ranges are on the buttons, but that’s a pattern in the category and not something specific about this model.
IntoYou describes the motor as powerful and quiet, both on the product page and on its questions-and-answers page, where the wording is that the products have quiet, high-performance motors that are supposed to deliver performance without disturbing noise.
The manufacturer does not publish any measured decibel value, either on the product page or anywhere else. None of the four Swedish shops provides a number either. Websites that state an exact decibel value for Ascen either provide their own measurement or a value without a source, and there’s no reason to trust a number that can’t be traced back.
What can, on the other hand, be established is that impact vibrators, as a category, are more audible than plain vibrators. The reason is mechanical: an impact motor moves a mass back and forth along an axis, and that movement creates both a working sound from the mechanism and a force that’s transferred to the surface. A vibration motor has no corresponding strike. That’s why the manufacturer markets the model as quiet should be read in relation to other impact vibrators, not in relation to a small bullet vibrator.
A practical tip that applies regardless of model: place the product on a soft surface between uses and avoid letting it work against a hard tabletop. A tabletop acts as a resonance box and noticeably amplifies the sound, and the effect is greater for a push vibrator than for any other product type in the category.
The manufacturer states that the Ascen is waterproof, and all stores write water-resistant or waterproof. No IPX rating is provided by the manufacturer, nor by any store. This is a shortcoming, and it is one of the clearest differences versus the more expensive competitors.
The IP system comes from the international standard IEC 60529, which defines enclosure classes for electrical equipment. The second number indicates protection against water: IPX4 covers splashes from all directions, IPX6 covers powerful water jets, and IPX7 means the product has been tested for immersion in water to a depth of one meter for 30 minutes. The difference between splash protection and immersion is significant in practice— a splash-safe product can handle a damp cloth and possibly a shower, but not a bathtub.
The word "waterproof" without a rating doesn’t say which of these applies. Both Fun Factory and We-Vibe state IPX7 for Bi Stronic Arc and Nova 2 respectively, so that’s a number that can be checked against a standard. IntoYou uses an adjective. On its questions-and-answers page, the manufacturer writes that most models are water-resistant or submersible, which suggests that the range includes both variants—but without saying which category Ascen belongs to.
That’s why the practical advice is cautious: rinse the product under running water, but don’t treat it as bathtub-safe until the manufacturer specifies the rating. Don’t immerse it, and pay special attention to the seams around the gold-colored base plate, which is the point where a housing of this type normally lets water in first.
Rinse the product in lukewarm water after each use and use fragrance-free soap or a cleaning product intended for intimate products. Spend extra time on the two seams—around the gold ring on the clitoris arm and around the base plate—and on the grooves in the shaft’s ridged surface, which Joyland describes as ridged and silky-smooth. Grooves are good for the feel and worse for cleaning. Wipe it off with a clean towel and let it air-dry before putting the product away.
The lubricant question has an unambiguous answer. The manufacturer states that the product is compatible with water-based lubricant, and Joyland lists water-based as the recommended lubricant. Silicone-based lubricant should not be used on silicone products — it breaks down the silicone surface over time and makes it porous, and a porous surface can no longer be cleaned properly; you can only replace it. Oil-based products such as coconut oil leave a film that is difficult to remove and that can also get trapped in the ridges.
The storage pouch or other included shipping contents are not published by the manufacturer. The only thing that can be confirmed is that a magnetic charging cable must be included, because the product can’t be charged without it. What the package otherwise contains — pouch, quick guide, safety information — is not stated in any of the sources.
The manufacturer lists three numbers in a row on the product page: battery 57 mAh, charging 50 minutes, and autonomy up to 100 minutes. The same three numbers appear on both the Spanish and the English versions of the product page, so it’s not a translation mistake.
With a magnetic charging cable that connects to USB. The manufacturer’s own image shows the cable: a white cable with a magnetic head that attaches to the contact points on the gold-colored plate at the product’s base. The charging time is stated as 50 minutes.
Magnetic charging is a trade-off, not a pure advantage. The advantage is that you don’t need an opening in the housing, which makes achieving water resistance easier and removes the rubber plug that would otherwise be the most common weakness on a cheap waterproof product. The downside is that the cable is product-specific: if you lose the charging cable, no standard USB-C cable works, so you have to get a replacement. It’s a real difference compared with Fun Factory Bi Stronic Arc, which according to the manufacturer is charged with standard USB-C.
A charging time of 50 minutes is short. For comparison, We-Vibe lists up to 90 minutes for Nova 2, and Lelo lists two hours for Ina Wave 2. A short charging time is a genuine convenience advantage, but it’s tied to the next question.
The text needs to be straightforward here. 57 mAh is a remarkably small capacity for a product with three motors, one of which is a jolt motor, and it’s hard to reconcile the figure with an operating time of up to 100 minutes.
Put it in context. Lelo states 520 mAh and 3.7 volts for the Ina Wave 2, and a runtime of up to two hours—so roughly nine times the capacity for just over the same runtime, on a product with a single vibration motor and a wave motion. A thrust mechanism normally draws more current than a vibration motor, not less, because it moves mass instead of just shaking it. The idea that Ascen could run for 100 minutes with three motors on a ninth of Lelo’s cell doesn’t add up with this physics.
So what can be established is that the manufacturer’s three numbers—57 mAh, 50 minutes of charging, and 100 minutes of operation—are not mutually consistent, and that the manufacturer does not publish the battery’s voltage, which makes it impossible to convert the capacity into energy. Without the voltage, you can’t compare the cell with any other model at all. The most likely explanation is an error in the product sheet, not a real 57 mAh cell, but that’s an interpretation and not a fact—and therefore the correct conclusion is that the runtime of 100 minutes should be read as the manufacturer’s stated figure, and the capacity number should be treated as tentative until it’s specified.
What generally applies to lithium-ion batteries also applies here: capacity drops with the number of charge cycles, and the product does best when it’s charged regularly instead of being stored fully discharged. If the battery is replaceable, the manufacturer does not say, but on a waterproof product without visible screws, the answer in practice is no. With use a couple of times a week, it’s the battery—not the silicone—that sets the limit for the lifespan.
We do not have price data from shops in your market yet.
Three independent motors with ten positions each for 595 SEK is unusually much, but what you pay for is that half of the specification is never published.
Three comparisons are relevant: versus the most established thrust vibrator in the category, versus the most established app-controlled rabbit model, and versus a rabbit with motion technology from a brand that publishes complete data. All the information below comes from each manufacturer’s own specifications.
Fun Factory Bi Stronic Arc is the direct functional equivalent: a thrust vibrator with a clitoral arm. Fun Factory states a total length of 223 millimeters, a diameter of 79 millimeters, and a weight of 336 grams; materials are silicone, ABS plastic, and polycarbonate; eight thrust programs and six vibration programs; an enclosure rating of IPX7; and charging via USB-C.
The differences that actually matter go both ways. Fun Factory publishes weight and an IPX rating and uses standard USB-C—three things IntoYou doesn’t do. Ascen, on the other hand, has app control, which Bi Stronic Arc doesn’t have; three independent motors versus Fun Factory’s two sets of programs; and ten thrust modes versus eight. On paper, Ascen is also longer, 248 versus 223 millimeters, while Bi Stronic Arc is significantly thicker.
Conclusion: if you want shock stimulation with documentation in order and a cable you already have at home, Fun Factory is the safer choice. If you want shock stimulation with an app, and you accept that the specification is more lightweight, Ascen is the cheaper option.
We-Vibe Nova 2 is the app-controlled rabbit model that most people compare against. We-Vibe lists the dimensions 217 × 85 × 39 millimeters, body-friendly silicone without phthalates, BPA, or latex, a lithium-ion battery that charges via USB, operating time up to 120 minutes, charging time up to 90 minutes, IPX7 ingress protection rating, app control, and a two-year warranty.
Nova 2 therefore has a longer operating time, a published IP rating, and a materials declaration that is specific to the model rather than to the range. Ascen has a shorter charging time — 50 vs. 90 minutes — three independent motors instead of Nova 2’s two, and a thrusting motion that Nova 2 doesn’t have at all. Nova 2 works with a flexible clitoral arm that follows the body, another solution to the same problem.
And one area where Ascen actually wins: the warranty. IntoYou states a three-year warranty on all products, compared with We-Vibe’s two years. That’s one extra year on a product that costs significantly less — and on a product category with moving parts, the warranty period isn’t a side note.
Lelo Ina Wave 2 is included here primarily as a measuring stick for documentation. Lelo lists the dimensions 200 × 65 × 45 millimeters, insertable length 110 millimeters, diameter 37.09 millimeters, weight 176 grams, a lithium-ion battery of 520 mAh and 3.7 volts, charging time two hours, operating time up to two hours, twelve modes, body-friendly silicone and ABS plastic, and a two-year warranty followed by a ten-year quality warranty.
Every line in that list is a line that’s missing or is incomplete with IntoYou: insertable length (only available as a store listing), weight (completely missing), battery voltage (missing), material breakdown by part (missing). This isn’t the same as saying the product is worse — Ina Wave 2 has neither a thrusting motion nor app control — but it’s a clear illustration of what you’re paying extra for with a premium brand in addition to the product itself.
Functionally, the three models are different answers to the same question. Ina Wave 2 makes a wave motion toward the G-spot, Nova 2 keeps contact with the clitoris during movement, Bi Stronic Arc thrusts, and Ascen does three things at once. If you already know which motion works, you should choose based on that, not on the number of modes.
Four Swedish stores sell the item with EAN 8436615002986. Cheapest are Blush Me and SexleksakerOutlet at 595 SEK each, closely followed by Vuxen at 596 SEK. The most expensive is Joyland at 795 SEK. That’s 200 SEK or a 34 percent difference for the exact same item number and the same color.
The inventory situation is unusually good for this category: all four stores had the product in stock during the price check on September 12, 2026. That means the price spread is real and not an artifact of cheap stores happen to be sold out—you can actually buy it for 595 SEK today. The difference between the cheapest and the most expensive store is, in practice, the entire amount you save, which is unusual: for most products in our register, the cheapest store is sold out.
Blush Me also lists 795 SEK as the regular price versus the campaign price of 595 SEK, which is the same figure that Joyland charges. This suggests that 795 SEK is the recommended price in Sweden and that three out of four stores are currently below it. It’s worth knowing if you compare in a few months and the price has crept back up.
The prices in the table above are updated when the stores’ product feeds are updated, but always check the final price at checkout. Shipping costs are added at most stores under a certain order value, and in this price range several stores are below the threshold for free shipping—which can eat up some of the 200 kronor.
It’s for you if you want to try thrusting technology without spending premium money on it. Getting a mechanical thrusting motion, a separate shaft vibration, and your own clitoral motor for 595 SEK is in itself remarkable—Fun Factory Bi Stronic Arc and We-Vibe Nova 2 are in a completely different price class. It’s for you if you want app control but don’t want to hand over an email address, because ActiveJoy, according to the manufacturer, neither requires an account nor stores personal data. And it’s for you if you want to be able to control three functions separately instead of being locked into a program that determines everything at once.
It’s not for you if you require a published IPX rating before you put a product in the bathtub—the manufacturer writes “waterproof” without a rating, and that’s not enough to justify submersion. It’s not for you if you want to know exactly what you’re buying before you buy it: the weight, what’s included in the delivery, battery voltage, the breakdown of materials per part, and a manual are all missing from the manufacturer’s materials, and the stated capacity figure of 57 mAh doesn’t add up with the stated operating time. It’s also not for you if you want to be able to charge with the same cable as your phone, because the charging cable is magnetic and product-specific.
One more thing belongs in the decision. Ascen is a relatively large product—248 millimeters total length, according to a store listing 13 centimeters insertable—with a moving mechanism and its own charging cable. That makes it a main product to have at home, not something to toss in your toiletry bag before a trip. If you want something small and easy to bring with you, you’ll need to look somewhere else in the range.
IntoYou offers three years of warranty on all products, and states that the warranty applies in accordance with applicable EU legislation and that manufacturing defects are handled by the manufacturer’s own customer service. Three years is one year more than We-Vibes’s two and the same as the Swedish right to complain. In practice, this means that the manufacturer warranty here does not give you anything beyond what you already have under the law, but that it is also not shorter.
What the warranty excludes that the manufacturer does not publish. There are no warranty terms in the text, no listing of wear parts, and no information on whether the charging cable is covered. With brands that publish their terms, charging cables and wear parts are usually expressly excluded, so assume that a broken charging cable will be your own cost until the manufacturer says something else.
The manufacturer also states that opened intimate products are not accepted for return for hygiene and safety reasons, except in the case of manufacturing defects. This aligns with how Swedish shops handle this category, but it’s worth reading before you break the seal.
What always applies, however, are your statutory rights. Under konsumentköplagen, you have three years of right to complain in case of defects in the item, regardless of what the manufacturer promises. For distance purchases, you also have a right of withdrawal for fourteen days under lagen om distansavtal och avtal utanför affärslokaler. Be aware that in practice the right of withdrawal is limited for hygiene items that have been removed from a sealed package—however, the right to complain for defects always applies. If you have questions about what applies in your case, Konsumentverket guides you via Hallå konsument.
