If you have been disappointed with previous experiences, with a dual action vibrator, you need to try this one. I loved that I could really customize my experience with this one, due to the many settings! The size is great, and it hits all the right spots. I threw away my other dual action vibe, because it pales in comparison to this one. This product us made of PVC, and may contain phthalates. These use 3 AA Batteries, I would suggest getting some rechargeables!
