Silver six is a controlled-type of bullet vibe by Shaki Toys. It has six little bumps, It's connected to a short 5-6 inch cord. The remote has a slide control-controller; you slide the button up or down to change the settings of the vibrations. That runs on two double A batteries, that makes it good, because if you are short on batteries you can borrow the ones form your television remote. The vibrations are not ground breaking, but they are enough to get you off.
