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 Zumios 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 tip, providing a less intense experience. Zumios mechanical design adjusts the intensity based on the pressure you apply. Push down harder, and the intensity increases. Push lightly, and the intensity decreases.
