The soft silicone tip of the Smart Wands™ responds to skin contact with a dynamic increase in massage intensity, thanks to its special SenseTouch™ technology. The rechargeable Li-Ion batteries make for a high-performance, cordless massage device that only makes a discreet buzzing sound. The appliance is waterproof for use in the shower or bathtub. It has eight different pulsation modes, which allow users to have an individual, pampering massage, anytime and anywhere.
