Rocks-Off Rude Boy 7-speed: review
Rocks-Off’s best-selling prostate massager reviewed against the manufacturer’s own specifications and price data from six shops. Platinum-hardened silicone without phthalates, TPE, or latex, a detachable RO-80mm bullet with seven modes, a replaceable LR1 battery instead of a charging cable, and IPX7 according to the manufacturer — but neither runtime nor sound level is published, and the shops cannot agree on how long the product is.
My rating
The most repairable prostate vibrator in the comparison. The Bulleten is detachable and sold separately; the battery is a replaceable LR1 instead of a fixed-soldered lithium-ion cell, and the silicone is platinum-hardened without phthalates, TPE, or latex. What you pay for is an interface with three constant speeds and four patterns controlled by a single button, an unusual battery format, and a specification where neither runtime nor sound level is published.
- Seven modes: three constant speeds and four patterns
- Platinum-hardened silicone and ABS — without phthalates, TPE, and latex
- 115 × 120 × 40 mm, 180 g — the family’s medium size
- Replaceable LR1 (N) battery included — no charging cable is included
- IPX7 according to the manufacturer — submersion 1 m for 30 min
- In this market, it’s sold by Rocks Off and Harmony.
Rocks-Off Rude Boy 7-speed — in brief — this is what you get
Rude Boy is the model that made Rocks-Off a name in the prostate category, and it’s still the middle model in the manufacturer’s so-called boys family. The shape is a closed C-curve in silicone: one end is an angled head that is inserted and placed against the prostate, and the other end is a broad outer base that rests against the perineum. A removable bullet vibrator sits in the base, and it’s that which drives the entire construction.
The manufacturer’s specification looks like this: the product dimensions are 115 × 120 × 40 millimeters, the weight is 180 grams, the material is silicone and ABS plastic, the drive is the seven-speed RO-80mm bullet that Rocks-Off uses throughout the entire range, the battery is N-size and included, and the product is listed as 100 percent waterproof. The manufacturer’s item number is 7RBKV-FB022. In this market, the item is sold by Rocks Off at GBP 29.99 and in stock, and by Harmony at GBP 29.99 and out of stock (price checked on 26 September 2026).
This review is exclusively about the black variant with EAN 811041011586. The number is confirmed in two independent ways: another retailer states it in its specification table, and a separate product page source states the same number in the gtin13 field in the product page’s source code. The manufacturer’s own product page, of course, publishes a gtin field, but in numeric format 8.11E+11 — a number that starts with 811, so it is consistent with the number, but not in itself sufficient evidence. It’s worth checking the number when you compare prices, since Rocks-Off sells five closely related prostate massagers with the same material and the same bullet, and shop listings mix them up.
What the “hands-free” design actually means
The manufacturer describes Rude Boy as a hands-free product with dual-acting stimulation of the prostate and perineum, and the wording is more technical than it sounds. A prostate massager without an outer arm must be held in place or pushed manually. Rude Boy’s arched shape instead means that the outer base supports the product against the body when you’re sitting, lying down, or standing, while the inner part is kept in position by the arch’s own tension.
In practice, that means two things. First, that the vibration reaches two points at the same time without anything needing to be held in place— the bullet vibrator sits in the outer base, i.e. directly against the perineum, while simultaneously transferring movement through the silicone up to the inner head. Second, that the design depends on whether the arch’s angle matches your anatomy. An arched prostate massager isn’t adjustable; it either fits correctly or it doesn’t. What can be established is that Rocks-Off sells five different arches with different measurements and angles within the same family, which is a reasonable indication that the manufacturer themselves considers fit to be the deciding factor.
The wide base also serves a safety function. It sits on the outside of the body and functions as a stop, which is the basic design requirement that every anal product must meet. According to the manufacturer’s own product images, the underside of the base is flat, which means the product can rest against a surface when it’s in place.
Naughty Boy, Rude Boy, Bad Boy, or Big Boy — which is which?
Rocks-Off names its prostate massagers by size rather than generation, and since all parts use the same material, the same battery, and the same bullet, it’s only the measurements and shape that differ. The manufacturer publishes a product measurement for each one, making the family above unusually easy to compare:
- O-Boy — 100 × 98 × 33 millimeters, 92 grams. The manufacturer’s narrowest and lightest hands-free model, described as intended for first-time users.
- Naughty Boy — 97 × 115 × 36 millimeters, 114 grams. The shortest of the actual arches, with an angled head and a beginner-oriented focus.
- Rude Boy — 115 × 120 × 40 millimeters, 180 grams. The model this text is about, and what the manufacturer themselves calls the mid-size.
- Bad Boy — 120 × 122 × 38 millimeters, 184 grams. The manufacturer describes it as Rude Boy with increased circumference and added contours.
- Big Boy — 120 × 123 × 40 millimeters, 222 grams. The family’s largest, and 42 grams heavier than Rude Boy.
There’s one detail worth paying attention to, because it contradicts how the models are usually described in store listings. The retailer states that Naughty Boy is the slimmer one and Bad Boy the rougher one, and that matches the manufacturer’s own wording. But the manufacturer’s own measurements show that Bad Boy is listed as 38 millimeters in its third dimension compared with Rude Boys’ 40 millimeters, so not rougher in that dimension, while Bad Boy is five millimeters longer and two millimeters wider. According to the manufacturer’s description, the difference lies in the contours rather than in an unambiguously larger overall circumference. So someone who chooses based on numbers alone gets a less dramatic difference than the marketing implies.
Material and build quality: platinum-hardened silicone and ABS
The material issue is the only characteristic of an anal product that can’t be compensated for with experience or care, and it determines whether the product is still hygienic after five years. Rocks-Off lists two materials for Rude Boy: silicone and ABS plastic. The silicone makes up the entire molded arched frame, meaning everything that touches the body, while the ABS plastic sits in the casing of the bullet vibrator.
What platinum-hardened silicone means in practice
The manufacturer is unusually specific on this point. Rocks-Off states that the silicone is platinum-hardened and describes it as the purest silicone, of the same type used in the medical and food industries, because it doesn’t produce toxic byproducts unlike peroxide- and tin-hardened silicone. It’s a material specification at a higher level of detail than what this product category normally publishes, where "body-safe silicone" is the usual claim and the curing method is almost never mentioned.
Why it matters: the curing method determines which residual products remain in the polymer. Platinum curing uses a platinum catalyst and, in practice, leaves no byproducts, while peroxide curing produces residual products that must be baked out and that can cause odor or residue on the surface over time. For a product that’s supposed to sit against mucous membranes during repeated uses, the difference is between a surface that stays the same and a surface that slowly changes.
Just as important is that the silicone is non-porous. A non-porous surface can be cleaned, because there are no microscopic cavities where residues can remain. It’s the single most important property of a material that’s introduced into the body, and that’s why the material declaration weighs more heavily than almost every other line in a specification. The ABS plastic in the bullet’s casing, in turn, is chemically inert according to the manufacturer, which means it doesn’t react with lubricants—however, it sits inside the silicone and normally doesn’t come into contact with the body at all.
Phthalates, TPE, and latex — why the material declaration is important
Phthalates are a group of softeners used to make plastic, especially flexible PVC, pliable. The Swedish Chemicals Agency describes them as substances that can affect the hormone system and make reproduction more difficult, and several of them are therefore restricted or banned within the EU in a large number of products. This category is a recurring subject of supervision, because it contains soft plastic against the mucous membrane.
Rocks-Off takes a tougher stance than most. The manufacturer explicitly states zero tolerance for phthalates, and additionally adds TPE and thermoplastic elastomers in the same sentence—so not just the softeners, but the entire material class in which they are usually found. That is a relevant tightening up, because “TPE” and “jelly rubber” are terms that say nothing at all about which softeners are included. The product data also labels the product as body-safe and free from phthalates.
The latex issue is addressed separately. Rocks-Off states that latex is not used in any of its products, and justifies that both by saying that latex is a common allergen and that it is porous, and therefore less hygienic. Latex allergy causes reactions on the mucous membrane faster than on normal skin, and an anal product is therefore exactly the use where the information matters.
Dimensions and weight: 115 × 120 × 40 mm—and three shops that say three different things
The manufacturer’s measurements are 115 × 120 × 40 millimeters, and the weight is 180 grams. Those three figures are an enclosing box, not a length in the direction of use: 115 millimeters is one dimension of the frame, 120 millimeters the other, and 40 millimeters is the product’s thickness at the thickest point. A C-shaped product has no single “length,” and that is the reason the shops can’t agree.
And they really can’t. Three shops state three different lengths for the same item number. One shop gives total length as 12 centimeters. Another gives 12.5 centimeters. A third gives 13.4 centimeters. None of them matches exactly the manufacturer’s 115 or 120 millimeters, and the 14-millimeter spread between the extremes is larger than what a rounding error could explain. The manufacturer’s specification applies; the shop figures should be read as different ways of measuring the same frame.
On the diameter, however, the shops agree. They all state 3 centimeters, and one shop also specifies that the insertable diameter is the same 3 centimeters. That figure is consistent with the manufacturer’s 40 millimeters, because 40 millimeters is the product’s greatest thickness, including the outer base, while 3 centimeters refers to the shaft itself. That is the figure that actually matters for the person choosing a size.
A store description should, however, be treated with caution. Two stores publish the same translated product text, where it says that the product is three and a half inches at its widest point and has a retractable length of six and a quarter inches. Six and a quarter inches is almost 160 millimeter, so it’s longer than the product’s largest overall dimensions according to the manufacturer. The retractable length of 6¼ inches cannot be reconciled with the manufacturer’s specification, and three and a half inches is reasonably a circumference that in the translation has been turned into a width—3½ inches in circumference corresponds to just over 28 millimeter in diameter, which is close to the 3 centimeters the other three stores state. Read that text as a mistranslation, not as a measurement.
The packaging information comes from only one store. It lists the packaging dimensions as 21.0 × 14.5 × 5.5 centimeters and a packaging weight of 0.31 kilogram. The difference versus the manufacturer’s 180 grams is therefore 130 grams of cardboard, blister, and battery—a reminder that shipping weight and product weight are two different figures, and that it’s the product weight that indicates something about how the product behaves when in use.
Seven modes, one button, and a removable bullet
The interface on Rude Boy consists of exactly one button, and it isn’t on the product itself but at the end of the bullet vibrator. One retailer describes the control as a built-in push button, and the manufacturer’s own product images show it as a small rubber button at the bullet’s rear end, accessible when the bullet sits in the base. You switch between the modes with repeated presses and turn it off with a long press.
That’s the simplest control imaginable, and it’s both the strength and the limitation. There’s no display, no remote control, and no app. At the same time, one single button means there’s nothing to learn, and the control can be found by feel—something that’s relevant because the button is on the back of the body when the product is in place.
How the seven modes are distributed: three speeds and four patterns
The number seven shows up in every source, but only two of them break it down. Those two sources state that the seven settings consist of three constant speeds and four vibration patterns. The manufacturer itself only states that the bullet is a seven-speed RO-80mm, without specifying the breakdown.
In practice, this means you have three levels of even vibration and four pulsating programs. It’s another matter than seven intensity steps, and the difference is worth knowing before you buy: if you want to fine-tune the strength, you have three steps to choose from, not seven. Compared with a modern rechargeable prostate vibrator, there are few steps—Lelo states ten settings for the Hugo 2, of which four are built in and six are available via the app—but if you compare with the rest of Rocks-Off’s own range, it’s seven that are offered across the entire boys family, since all five models use the same bullet.
What can be stated purely from a construction standpoint is that the vibration source sits in the outer base, not in the inner head. The vibration against the prostate is therefore transferred through the silicone rather than generated on the spot. That is the principal difference versus models that have the motor in the insert part, and it’s a trade-off: the transfer dampens the vibration on the way, but at the same time it provides a direct and undamped vibration to the perineum, which is the whole point of the construction.
RO-80mm: the bullet that is simultaneously its own product
The bullet vibrator is removable, and that’s the detail in this product that has the most consequences. The manufacturer sells the same bullet separately as RO-80 7-Speed Special Edition, and publishes its specifications: 15 × 82 × 15 millimeters, 24 grams, silicone and ABS plastic, battery in N size, and a waterproof construction.
That leads to three practical consequences. The first is hygienic: because the bullet can be taken out, the silicone cavity in the base can be rinsed through separately, instead of a fixed motor making the cavity inaccessible. The second is in terms of repairability: if the vibrator stops working, it’s the bullet that’s broken, not the silicone ring, and the bullet can be replaced as a separate item. The third is that the bullet works independently, meaning that in practice you get two products in one package.
The downside of the same construction is that there’s a seam. The transition between the bullet and the silicone cavity is a joint where water and lubricant can end up sitting, and it has to be dried out. A one-piece product without an opening doesn’t have that problem—but it also can’t be repaired.
Travel protection: why the button has to be held in for 3–4 seconds
A note in the manufacturer’s service instructions explains something that otherwise reads like a fault. Rocks-Off states that the power button must be held down for three to four seconds for the product to start, and that this is due to a built-in travel lock. The function exists so the product doesn’t start on its own in a bag.
The same page also brings up two more points that rarely appear in store texts. Before first use, the insulator between the battery and the contacts must be removed—a small plastic tab that otherwise makes the product seem dead in the packaging. And the manufacturer explicitly advises against rechargeable batteries in its products, reasoning that they lack sufficient voltage for full power. It’s a specific and verifiable instruction, and it’s relevant for anyone who reflexively buys rechargeable cells instead of disposable batteries.
Sound level: what Rocks-Off says and what they don’t say
Here the answer has to be short and honest. Rocks-Off does not publish any measured decibel value for the Rude Boy, either on the product page or in the care instructions, and neither of the two shops selling it in this market provides any number either. One shop describes the vibration strength as strong, which is a strength statement and not a sound level, and that’s as close as this product’s documentation gets to an actual message.
What can, however, be established is the design premise. The vibration is generated by an eccentric motor inside a hard ABS casing, which in turn sits in a cavity in the silicone. Such a construction dampens some of the sound through the silicone, but the cavity also acts as a small resonance chamber. Figures for the sound level for this model that appear on other sites are not covered by the manufacturer, and anyone who places importance on being quiet should treat the question as unanswered rather than as answered in any particular direction.
A practical tip that applies regardless of model: place the product on a soft surface between uses. A hard tabletop works as a resonance box and noticeably amplifies the sound.
Water resistance: IPX7 according to the manufacturer—and a store that contradicts it
The manufacturer’s product page lists the Rude Boy as 100 percent waterproof, and the manufacturer’s care page goes further and prints the classification: all Rocks Off products are stated to be 100 percent IPX7 waterproof and submersible for play in the bath. Three of the six stores repeat the claim. One store lists water resistance: yes, another lists water resistance: yes, and two other stores write that the product is 100 percent waterproof and fully submersible. In this market, it is sold by Rocks Off at GBP 29.99 and in stock, and by Harmony at GBP 29.99 and out of stock (price checked on 26 September 2026).
Another shop says otherwise. In its product text, the shop writes that the product is splash-proof but not waterproof, that it should not be fully submerged in water, and that it should not be used in the bathtub, and in the specification table it states that water resistance is given as splash-proof. This is a discrepancy in the opposite direction compared with the manufacturer and with four other shops. The manufacturer’s instructions apply, but the discrepancy is worth reporting — among other things because a buyer who reads that exact page may think the product is worse than it is, and because shop texts that deviate like this are often written generically rather than being specific to the product. In this market, it is sold by Rocks Off at GBP 29.99 and in stock, and by Harmony at GBP 29.99 and out of stock (price checked on 26 September 2026).
What IPX7 means according to IEC 60529
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. The letter X in the first position means that no dust protection has been tested, not that the protection is missing.
The difference from 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. With IPX7, the entire product can be rinsed off without extra care, and that is a genuine advantage for an anal product specifically, where careful cleaning after each use isn’t a preference but a requirement. If a product lacks an IPX rating 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 manufacturer’s instructions are short and clear. Clean with soap and water or with an antibacterial toy cleaner, and do not use dish soap or alcohol-based products, because they can damage the surface. Remove the bullet and rinse the cavity separately — that’s the only part where water and residue can remain standing. Dry thoroughly and let it air-dry before putting the product away.
On the lubricant question, the manufacturer is categorical: only water-based lubricant should be used with Rocks-Off products. A specification table repeats the same recommendation. 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, only replaced. Oil-based products such as coconut oil leave behind a film that’s hard to remove. For an anal product, lubricant also isn’t optional, because the area does not produce its own moisture.
A storage instruction in the manufacturer’s material deserves its own section, because it rarely appears anywhere else. Rocks-Off writes that their products should be stored separately from other brands, with the justification that lower-quality toys in jelly material can damage premium silicone on contact. It’s a concrete and practical message: don’t put this in the same drawer as a soft jelly product. The battery-operation instruction is to remove the battery when the product is not in use, to avoid leakage.
Battery: an LR1 instead of a built-in lithium-ion battery
This is where the single biggest difference is, compared with almost everything else in the price range. Rude Boy has no built-in rechargeable battery. The manufacturer lists the battery as N size and writes that a battery is included. Three stores specify the designation: one listing states a power output of 1 × LR1 (N) with battery included and lists the delivery contents as the prostate massager plus an LR1 (N) battery; another lists the battery type as LR1 (N) in a unit that comes with it; and another lists N battery as included. It is sold by Rocks Off and Harmony.
How is the Rocks-Off Rude Boy charged? The answer is that it isn’t charged
There is no charging cable, no charging port, and no charging time, because the product is powered by a replaceable disposable battery. LR1 is an alkaline cell in N size, meaning a format that’s smaller than AAA and significantly less common in retail.
It’s a trade-off with clear pros and cons on both sides. The advantages are real: the product never dies from a worn-out cell, because the cell is replaced—which is the most common service-life limitation on rechargeable intimate products, where a fixed-in lithium-ion battery makes the entire product unusable when it loses capacity. There’s no proprietary charging cable to misplace, and no opening in the casing for charging, which makes IPX7 easier to achieve structurally. The product can also be taken with you without a charger.
The disadvantages are just as real. LR1 isn’t sold in every grocery store, and someone who runs out of battery in the middle of the week may need to place an order for new ones. Running costs are ongoing instead of zero. And the manufacturer advises against rechargeable cells, citing insufficient voltage, which in practice shuts the door on solving the disposable-battery question with rechargeable batteries. Expect to buy a multi-pack of LR1 at the same time as the product—that’s the only preparation that’s really required.
The operating time that isn’t published
Rocks Off does not publish any operating time for the Rude Boy, either in hours or in number of uses per battery, and Harmony does not indicate any value either. It’s therefore not possible to say how long an LR1 lasts in this product, and any figure that circulates somewhere else is not supported by the manufacturer.
There is a real gap in the specifications, and it’s worth noting exactly this because competitors publish their corresponding figures. Lelo states for the Hugo 2 a lithium-ion battery of 420 mAh and 3.7 volts, a runtime of up to one hour, and a charging time of up to two hours at 5.0 volts and 500 milliamps. Without a corresponding statement from Rocks-Off, it isn’t possible to convert the runtime to power consumption, and it isn’t possible to compare how many hours of use a battery corresponds to between the models.
Where can you buy it — and what does it cost?
2 shops sell this product. Lowest price £29.99, highest £29.99 — a difference of 0 per cent for exactly the same item. Prices were checked on 26 September 2026 and may have changed since.
The bullet can be replaced, and the battery can be replaced. That makes Rude Boy one of the few products in the category that isn’t considered disposable once the motor is.

Rude Boy compared with the alternatives
Three comparisons are relevant: against the smaller model in the same family, against the larger ones in the same family, and against a rechargeable prostate vibrator from another premium brand. All the information below comes from the respective manufacturers’ own specifications, and all prices are from the shops’ product feeds on September 12, 2026.
Against Rocks-Off Naughty Boy — 18 millimeters shorter arch
Naughty Boy is given by the manufacturer as 97 × 115 × 36 millimeters and 114 grams, versus Rude Boy’s 115 × 120 × 40 millimeters and 180 grams. So it is 18 millimeters shorter in the first dimension, 5 millimeters narrower in the second, 4 millimeters thinner, and 66 grams lighter — a third of the weight.
Everything else is identical. Same silicone and ABS, same N-size battery, same seven-speed RO-80mm bullet, same hands-free principle. The manufacturer describes Naughty Boy as the beginner model with an angled head, and the same role distribution is described: if you’re looking for something narrower, Naughty Boy is the way to go.
The conclusion is straightforward. The difference between the models is purely geometric. If you can choose based on experience rather than on function, Naughty Boy is the more cautious option, and Rude Boy is the next step — and the one who already knows that a 3-centimeter diameter works has no reason to pay for the smaller one.
Against Rocks-Off Bad Boy and Big Boy — what the four grams conceal
Bad Boy is listed as 120 × 122 × 38 millimeters and 184 grams. That means it is four grams heavier than Rude Boy, five millimeters longer, two millimeters wider — and two millimeters tunnare in the third dimension. The manufacturer describes Bad Boy as Rude Boy with increased circumference and added contours, intended for experienced users, and it’s the contours rather than an unambiguously larger measure that’s the difference.
Big Boy is the clearer step up: 120 × 123 × 40 millimeters and 222 grams, i.e., 42 grams heavier than Rude Boy and the family’s largest hands-free model according to the manufacturer. Here too, the materials, battery, and bullet are the same.
What can be established is that the whole family shares the same drive and materials, and that the choice therefore comes down to fit and nothing else. That makes Rocks-Off’s range unusually easy to navigate: you don’t pay for more functions when you go up in size—you pay for a different geometry. Rude Boy’s position as the mid model is, in that sense, the least risky guess if you don’t already know what fits.
Against Lelo Hugo 2 — rechargeable, app control, and ten settings, but one hour of runtime
The most interesting comparison goes beyond the brand. Lelo Hugo 2 is an arched prostate vibrator with the same basic idea—inward head toward the prostate, outer arm toward the perineum—but built on modern rechargeable technology. Lelo lists the dimensions as 104 × 107 × 41 millimeters, an insertable length of 72 millimeters, and a weight of 121 grams—so it’s a smaller and nearly 60 grams lighter product than Rude Boy.
The material is the same in practice: body-friendly silicone and ABS plastic. The products differ hardly at all there. The difference lies in the drive and control. Hugo 2 has a lithium-ion battery of 420 mAh and 3.7 volts, charges in up to two hours at 5.0 volts and 500 milliampere, and provides up to one hour of runtime. It has ten settings, four built-in and six available via the app, and according to Lelo it’s 100 percent waterproof. The warranty is two years, followed by a ten-year quality guarantee.
Put the two against each other and the picture becomes clear. Hugo 2 offers more settings, app control, and no disposable batteries—but it also only gives one hour of runtime per charge, and a battery that can’t be replaced once it’s out. Rude Boy has three speeds, four patterns, and a single button—but it has a cell you replace once and for all, and a bullet that’s a replaceable spare part. One is the more advanced product; the other is the more repairable. Price-wise, they’re not in the same class: Rude Boy is sold at Rocks Off and Harmony, and Lelo sells the Hugo 2 in a completely different price segment.
Sold at Rocks Off and Harmony in this market
Rocks Off and Harmony sell the item with EAN 811041011586.
However, the stock situation changes the math. One listing at the lowest price did not have the product in stock at the price check, while another did. Stores that list a product as sold out may keep an old price in the feed, and that price is rarely what you end up paying when the item is back in stock.
In this market, the product is sold by Rocks Off and Harmony. The variation in offers is therefore greater than you might expect from the headline numbers, which is a common pattern in this category and a reason to evaluate offers based on the final price instead of the discount percentage.
Price variation doesn’t depend on retailers selling another variant. Always check the final price at checkout—shipping can be decisive for which store is actually the cheapest.
Who is Rocks-Off Rude Boy for—and who is it not for?
It’s for you if you want a hands-free prostate massager in a medium size without having to worry about charging. It’s for you if you value that a broken vibrator can be repaired by replacing the bullet rather than throwing away the entire product. It’s for you who wants platinum-hardened silicone against the body, a detachable motor part that makes the hollow area cleanable, and a product that, according to the manufacturer, tolerates full submersion. And it’s for you if you want all of that.
It’s not for you if you want many intensity levels—three constant speeds isn’t much. It’s not for you if you want remote control or an app; neither is available, and if you want that, you’ll have to go to another manufacturer—Lelo Hugo 2 is the closest alternative with the same curved shape. It’s not for you if you refuse to keep disposable batteries at home, especially not in a format like LR1, and not for you who wants to be able to charge via USB like almost everything else in this price range. And it’s not for you if you require a published runtime and a measured sound level before buying, because Rocks-Off publishes neither for this model.
One more thing belongs in the decision. What determines whether a bow-shaped prostate massager works is not the number of settings, but whether the angle fits you, and that’s something no specification can answer. Rocks-Off sells five bows with different measurements in the same family for exactly that reason. Rude Boy is the middle option, and the manufacturer’s own figures show that stepping down to Naughty Boy is a matter of 18 millimeters and 66 grams, while stepping up to Big Boy is 5 millimeters and 42 grams. If you’re unsure, the middle option is the guess with the least distance to both extremes.
Warranty, complaints, and right of withdrawal
Rocks-Off provides a two-year warranty, but the terms include a limitation that’s easy to overlook: the warranty applies, according to the manufacturer, to goods purchased directly in Rocks-Off’s own web shop. So if you buy from Harmony, it’s the store—not the manufacturer—that is your counterparty. The manufacturer’s 30-day return window works the same way only for its own purchases, and it additionally requires the original packaging with an unbroken seal.
What always applies, on the other hand, are your statutory rights—and in practice, they are stronger than the manufacturer’s warranty in this case. In the EU and EEA, consumers buying online generally have a 14-day right of withdrawal, starting when the goods are received. And in the EU, the seller is liable for defects that exist at delivery and appear within at least 2 years (the legal guarantee).
Be aware that in practice the right of withdrawal can be limited for hygiene products that have been taken out of a sealed package. In the EU/EEA, consumers buying online generally have a 14-day right of withdrawal, starting when the goods are received. However, sealed goods that are not suitable for return for health or hygiene reasons are exempt from the right of withdrawal once unsealed. The right to complain about defects, however, always applies (the seller is liable for defects that exist at delivery and appear within at least 2 years).

Water-based—and only water-based. The manufacturer explicitly states that only water-based lubricant should be used with Rocks-Off products, and another retailer repeats the same recommendation in its specification table. Silicone-based lubricants break down the silicone surface over time and make it porous, which means it can no longer be cleaned properly. Oil-based products like coconut oil leave a film that is difficult to remove. For an anal product, lubricant is also not optional, because the area does not produce its own moisture. Clean with soap and water or antibacterial toy cleaner—the manufacturer advises against dish soap and alcohol-based products.
