If you were one of those guys who just wanted more from your Rude Boy, the Bad Boy offers a bigger and more bulbous shaft for advanced players and size queens alike. With all of the vibration of the original Rude Boy, the Bad Boy gives a more intense and full experience, with a shaft that has more girth and deeper curves, but maintains the length of the original. 1 x N battery. (5" x 1 3/4")
