A hard-bodied rigid design is ready for all your naughty action, and a single-button control cycles through 10 functions of intense vibration, pulsation, and escalation. But don't be intimidated: A smart button design and a state-of-the-art travel lock are built right into the toys controller button, for a one-stop-shop that remembers your last-used setting and will ensure complete silence when travelling. No more ""bump and vibe"" in the suitcase on the taxi ride home!
