- Fully waterproof build and smooth silicone surface made cleaning effortless and allows for use in the bath or shower
T here’s a moment, somewhere between unboxing and first use, where a product either earns your trust or quietly disappoints you. The Fun Factory Manta earned mine before I’d even switched it on.
The Fun Factory Manta doesn’t look like anything else in my testing rotation—and that’s precisely the point. Its elegant, wing-shaped silicone frame clips around the shaft while keeping the head fully exposed, a design decision that sounds simple until you realise almost nobody else has thought to do it. The seamless silicone is genuinely premium to the touch, the controls are two-button intuitive, and the motor delivers the kind of deep, rumbly vibration you feel rather than just hear—none of that tinny surface buzzing you get from Amazon’s plethora of suspiciously affordable alternatives.
Where it really earns its $124.99 price tag, though, is in partnered play. That open-frame design makes it one of the only vibrators of its kind that works with a partner rather than instead of one—slipping seamlessly into oral sex in a way that will make both of you wonder why it took this long for someone to design it properly. This is where it really sets itself apart from it’s edging rivals, the Lovense Gush and the Hot Octopuss Pulse Solo.
Design & Build Quality
One of the first things you notice about the Fun Factory Manta is how good it feels in your hand. The medical grade silicone feels smooth and premium, the ABS plastic casing is solid and polished and the buttons are raised and illuminated, making them easy to operate even when slippery or in the dark. Nothing about the Manta feels cheap or poorly designed. It has a comforting weight (120g) that’s evenly balanced, substantial without being unwieldy.
The design of the Manta is unique, looking almost like something an anal probing alien may endeavor to use upon a hapless Earthling. The star of the design is the aforementioned wing tips (or pincers), these are flexible and wrap around your penis, accommodating most penis sizes. The Manta delivers deep, rumbly vibrations and offers a wide range of power settings. It is equipped with 3 buttons, a power switch, a + button and a – button. After turning it on, you can hit the + button to increase intensity, or the – button to lower the power. The Manta has 6 power settings and 6 patterns in total, and when you first turn on the device it will start at the middle power setting, not the lowest setting. A great little feature that Fun Factory includes is that if you are using any of the patterns, you can simply hit the – button once and it will revert back to straight vibration at the highest power. This helps with navigating through the power and pattern settings more than you may think, especially in the heat of the moment.
Overall, the Fun Factory Manta does well to maintain the reputation of German engineering. It achieves a premium look and feel, feels solid and well put together, and most of all does exactly what it’s built to: Feels good.
Performance
This is where the Manta stops being an interesting concept and becomes a genuinely compelling product.
Switch it on at the mid-point setting — where it defaults — and the first thing that hits you is the quality of the vibration itself. It’s deep and rumbly in a way that you feel through the whole shaft rather than just at the point of contact. There’s none of that high-frequency surface buzzing that cheaper motors rely on, the kind that numbs more than it stimulates. Fun Factory’s motor has real depth to it, and on the Manta that depth is delivered through both wing-tips simultaneously, which creates a surrounding sensation that’s difficult to achieve any other way.
Where the Manta genuinely separates itself from everything else in its category is in partnered use. That open-frame design isn’t just an ergonomic nicety — it’s a fundamental rethinking of how a vibrator can function during sex. During oral play in particular, it operates alongside a partner rather than instead of one, adding layered vibration to an already pleasurable experience in a way that tends to produce a fairly unanimous reaction from everyone involved. It doesn’t obstruct, it doesn’t compete — it just quietly makes everything better.
If there’s a criticism, it’s that the wing-tips, while flexible, work best with a generous amount of lubricant. Without it, the silicone can drag slightly during gliding use. A small caveat for a product that otherwise delivers exactly what it promises.
Features
The Manta isn’t a product that buries you in gimmicks — and that restraint is itself a feature worth noting. What it does offer, it does with intention.
Waterproof — fully submersible, which means bath or shower use is entirely on the table, and cleanup is as simple as a rinse under the tap. For a toy with an open-frame design, the fact that water resistance has been engineered in without compromise is a quiet but meaningful detail.
USB Magnetic Charging — Fun Factory’s proprietary magnetic click-charge connection is secure, reliable, and mercifully free of the flimsy rubber port covers that plague lesser waterproof toys. A full charge takes roughly 120 minutes and delivers approximately 90 minutes of use — honest numbers, not optimistic ones.
Body-Safe Materials — the medical-grade silicone and ABS plastic are phthalate-free, non-porous, and fully body-safe. At this price point that should be a given, but in a market where certain budget alternatives make creative use of the term “silicone,” it’s worth stating plainly.
Whisper-Mode — at lower settings the Manta is impressively discreet. Crank it to maximum and it’s not silent, but it’s well within the range of plausible deniability. Thin walls and nosy housemates notwithstanding.
Inclusive Sizing — the flexible wing-tips accommodate a genuinely wide range of sizes without fuss or adjustment. It’s not something Fun Factory shouts about particularly loudly, but it’s the kind of thoughtful engineering decision that matters to a lot of people.
Value & Verdict
The Fun Factory Manta is a masterclass in doing one thing exceptionally well. It’s not trying to be an all-in-one solution or the most feature-packed toy on the market. Instead, it delivers focused, rumbly vibration exactly where it matters most—and it does so with build quality that justifies every dollar of its premium price tag.
After six months of regular use, my Manta performs identically to the day I unboxed it. The silicone is still flawless, the motor hasn’t weakened, and the buttons remain responsive. That kind of durability is rare in this category and speaks to Fun Factory’s German engineering reputation. This isn’t a toy you’ll replace in a year; it’s one you’ll still be reaching for in five.
The open-fork design initially seemed like a limitation to me—where’s the sleeve? Where’s the enveloping sensation? But in practice, that openness is the Manta’s greatest strength. It plays well with hands, mouths, and other toys in ways that closed designs simply can’t. Whether you’re using it solo or incorporating it into partnered play, it enhances rather than complicates.
Is it perfect? No. The lack of app connectivity will disappoint users who want remote control or custom patterns. The proprietary charging cable is mildly annoying. And if you’re expecting a traditional stroking sensation, you’ll need to recalibrate your expectations entirely—this is a vibrator, full stop.
But for what it sets out to do, the Manta executes flawlessly. Powerful, quiet, waterproof, durable, and dead simple to use. If targeted frenulum vibration sounds appealing to you—whether for solo edging, enhancing oral, or adding a new dimension to partnered play—the Manta earns its spot in your rotation.
