The Serenity Vibrator has become my new favorite toy. It's waterproof, and I used it in the shower. You can use it during masturbation or with your partner. It's great because of it being dual action. It has a curve in it that hits the G-spot and a clitoral attachment that stimulates you to a big orgasm. It is well worth the money and is a toy that I will continue to use in the future. I love it!
