I'm very impressed with this 'rabbit' and the amount of vibration it produces. My girlfriend has neglected all of the other toys she has and uses this one instead. The pleasure that it produces for her makes me jealous. Seriously. Also the way the two rabbit ears 'dual' vibrate when used on myself, create a 'different' feeling that is also very enjoyable myself. It has been used by myself and my girlfriend solo more than it had been used together so far.
