I've tried a few products with my girlfriend that involved prostate stimulation, and they were quite enjoyable. This one combines an amazing vibrating silicone butt plug, along with a cock ring that stretches completely around your penis and balls. The unit has two different vibrating devices in it, that make it next to impossible to concentrate when it is turned on. The remote works from a far distance, and my girlfriend enjoyed making me squirm with the 10 different speeds. It is one of the best items that we have ever bought. What an amazing pick! I have bought a few different items from this company, and the quality is top notch.
