Details:Unlock new sensations with Zumio S, the only toy that uses a rotating motion – not vibration – to deliver pinpoint stimulation exactly where you want it. The combination of Zumio’s unique SpiroTip™ rotation, 8 speeds, and pressure-sensitive intensity put you in complete control of your pleasure. Zumio S has a shorter stem and larger, silicone tip, providing a less intense experience than the Zumio X. Zumio’s mechanical design adjusts the intensity based on the pressure you apply. Push down harder, and the intensity increases. Push lightly, and the intensity decreases. Waterproof and USB Rechargeable.
