It's a solid and heavy vibrator, made of solid silicone. It's a bit too girthy for my average-girl tastes, but it'll stay put once in! The quiet of the vibrations is pleasing, unfortunately the strength is just a bit too low for those who love something strong in that department. It can tease pretty well for the variety of vibration settings it provides, not to mention a pleasure to use if in the shower or anywhere it might get a little too wet.
