Rechargeable, powerful, with 3 speeds and 2 vibration patterns. For those good vibrations, insert the large motor into your chosen shape, feel it click and lock into place, and get your own pleasure party started. When you want to change things up simple squeeze both sides of the shape and it will unlock from the motor. Who has time to replace batteries? The motor comes with a USB charging cable so you can easily charge at any time. Bodysafe. Ooh by Je Joue.
