The Extreme-O Vibe's discreet styling won't get in the way of just about any position or act, so it's perfect for bringing to bed with a partner and just as stupendous when flying solo. This vibe is definitely meant for external stimulation, and shouldn't be used for penetration, as there's no base to prevent too-deep slips. One reliable mode of vibration throbs through the lightweight shape with the touch of a button. In body safe, phthalate and fragrance free ABS plastic with a silky PU coating, the Extreme-O cleans easily and thoroughly using warm soapy water or a good toy cleaner. Requires 1 AAA battery.
