The Bliss rechargeable egg is so powerful...and it's controlled by a wireless remote. You can wear it anywhere (given that it is comfortable enough for you to wear that long). It was a little big for my taste, but if you don't mind the size of the egg, then you love it. The vibrations are strong and there are several to choose from. Congrats to Cal Exotics, I might actually use this more than four times.
Powerful, wireless, several settings, rechargeable, remote controlled
