If you are looking for a silent vibrator, then Silent Vibrations by Doc Johnson is definitely for you.
The elegantly designed vibes are made out of hard, smooth plastic that helps to deliver powerful stimulation where applied, ensuring that you reach the big O time and again.
This Silent Vibrations vibe has a probe design to it, so it's perfect for penetration. The head is smaller than the rest of it for comfort and ease of insertion so you could use it both vaginally and anally if you decided to.
The strong vibrations are perfect for any kind of stimulation that you desire and require, but this vibe is quiet enough that you can use it practically anywhere and people would hardly notice the noise.
The controls are simple and easy to use as well, there is a spin dial on the bottom that you use to turn on the vibe and adjust the speed to your liking.
