The best part of the Pocket Rocket is definitely the bumpy business end and the easy-on twist end. This vibrator is also perfectly sized for your hand. It fits easily in your palm and can be turned on and off with one hand. As I mentioned before, it only has one vibration setting. It would be better with a few setting options, but its one setting still gets the job done. It's a medium/gentle vibration, and it deteriorates as the battery loses power over time. For best results, use a fresh battery! The Pocket Rocket also has a medium noise level. If you're in a room, alone, with the door closed, you should be OK. I certainly wouldn't recommend using it in a dorm setting or anywhere with thin walls.
