I adore all of the Evolved Roulette vibrators I have, and the Bet On Black is no exception. It has some of the most powerful vibrations of any of the vibrators I have, and I really like the texture of this one. The wheel that controls the vibrations works well, it's easy to turn and much easier to regulate the vibration speed than models that have the dial on the bottom.
I'm dying to get this vibrator!!!
