Product Rating: 4 Stars - Extremely effective! | Power Rating: Mild - Enjoyable but not orgasm inducing. | Noise Rating: Inaudible - Almost silent. | Texture and material construction: The Vr1 should last you a long time, and it's made from body-safe silicone that is very soft and silky. It has no texture to it, and it inserts really easily with lubricant. | Review Details: The Vr1 is an interesting vaginal ball. It's actually the first of its kind. This is because, depending on how hard you squeeze this sex toy when it's inserted, it actually will vibrate harder or softer! The squeezing technique works relatively well, but sometimes, the toy can get moved around during insertion and it won't work as well. Sometimes it does require some fine adjustments if you want to use it with the "squeeze me" technology. You can also lock the toy for travel or when you don't want it to vibrate. The removal string is firmly attached to the toy and it doesn't break off and most women should be able to easily retain and feel pleasure by the size of this vaginal exerciser. I really like this toy and I'm hoping to see more toys designed just like it!
