They say two heads are better than one. And with Vivian, we agree. Her dual motors, located at the tips, may very well make Vivian the last pleasure object you ever buy. The twin motors double the pleasure with 10 functions of vibration and pulsation. Crafted from 100% medical grade silicone, Vivian is the ideal companion for a long soak in the tub. Best of all, Vivian does not require batteries because she is fully USB rechargeable. Just like your best friend, Vivian is always there for you. From Maia Toys.
