USB Bullet Heart Throb by Unihorn

USB Bullet Heart Throb by Unihorn is a rechargeable dual-motor bullet vibrator with independent vibration and pulsing controls that create 100 unique sensation combinations. Its compact silicone body and intuitive two-button system suit solo exploration or partnered play, while full waterproofing opens up bath and shower use.

What it is and how it's made

USB Bullet Heart Throb by Unihorn is a compact bullet vibrator engineered with two independent motors that work simultaneously or separately. The main motor delivers traditional vibration throughout the device, while a secondary motor powers a specialised pulsing mouth feature that mimics oral sensation. Body-safe silicone construction ensures soft contact and durability, with an ABS plastic base housing the controls and charging port. The playful unicorn design and charming pink finish make it visually approachable without sacrificing genuine power or build quality.

What distinguishes this vibrator is the genuine dual stimulation it offers within such a small footprint. Unlike metal vibrators, which deliver fixed intensity through solid construction alone, the Heart Throb's dual-motor architecture lets you layer sensations—running vibration and pulsing together, or switching between them mid-session. The 100 possible combination combinations mean each use feels fresh, and the magnetic USB charging keeps the waterproof seal intact.

Main features

• Dual-motor system: Independent vibration and pulsing mouth feature work together or separately, creating unprecedented customisation within a compact design.
• 100 unique combinations: Ten vibration patterns paired with ten pulsing rhythms let you discover new sensations across every session and explore what suits your body best.
• Intuitive two-button control: Wave symbol and mouth symbol buttons adjust each motor independently, cycling through patterns on demand without menu screens or confusion.
• Magnetic USB charging: Foolproof connection with no exposed ports means the waterproof integrity stays intact and charging becomes genuinely simple.
• 100% waterproof construction: Fully submersible silicone body opens up shower play, bath exploration, and hassle-free thorough cleaning under running water.

First use and settings

Charge the Heart Throb fully before your first session—the magnetic cable connects easily and takes about two hours from empty. Once powered, press the wave symbol button to cycle through the ten vibration patterns, starting with gentle and escalating to intense. Press the mouth symbol button separately to explore the ten pulsing rhythms. Many first-timers discover that running both motors at low intensity together creates a completely different sensation from either motor alone, so take time to experiment before pushing to maximum power.

Begin with a single pattern at low intensity to understand how your body responds to each type of stimulation. The pulsing mouth feature feels distinctly different from standard vibration, and combining patterns takes practice to dial in. If you're exploring tongue vibrators for the first time, remember that the Heart Throb's pulsing action mimics rather than perfectly replicates oral sensation—it's a distinct pleasure rather than an exact replica. Always apply water-based lubricant before use, and rinse thoroughly under running water after each session.

Who gets on with it

Care and storage

Rinse the Heart Throb under warm running water immediately after use, using a soft cloth or gentle hands to wipe the silicone. Never use soap or harsh chemicals, which can degrade the material over time. Dry completely with a lint-free cloth before storage to prevent moisture trapping. Store in a cool, dry place away from direct sunlight and heat; the included travel lock function keeps the buttons from activating accidentally in your bag or bedside drawer.

What to expect

The Heart Throb's compact size means it fits comfortably in your hand and suits both external and partnered use without awkwardness. First-timers often underestimate how different the pulsing mouth feature feels compared to traditional vibration—it's worth exploring at low intensity first to understand your preference. Many users discover they enjoy alternating between vibration and pulsing throughout a session rather than committing to one pattern.

Battery life of 60 minutes covers most sessions without interruption, but longer explorations may require a top-up charge mid-session. The magnetic charging connection is genuinely foolproof compared to traditional USB ports, so you won't struggle with positioning or alignment. Cleaning takes under a minute—warm water and a cloth—which keeps maintenance simple and the device hygienic.

The dual-motor system does mean slightly more weight than a single-motor bullet of the same size, but most users find the 120 grams substantial rather than burdensome. Noise level is moderate; it's audible in a quiet room but not as high-pitched or obvious as some smaller vibrators. The silicone body dampens sound compared to plastic or metal alternatives, making it discreet enough for shared living spaces.

Build quality holds up well with proper care; the silicone doesn't degrade quickly and the buttons remain responsive across hundreds of uses. Users who follow basic cleaning and storage practices report years of reliable use without performance drops or material breakdown.
