There's nothing better to bring a little sunshine into you sex life, than with a Rainbow Rhythms Vibrating Bullet. Made by Doc Johnson, these Rainbow Rhythms Vibrating Bullets come in a variety of exciting colours to brighten your life. You often hear it said that a small toy is extremely powerful for its size, but these little bullets really are. With full multi speed vibrations operated via the twist n go base, they are also waterproof and great fun in both the bath or shower. Mini Vibes don't come more powerful, waterproof or colourful than these Rainbow Rhythms. We doubt you will find anything cheaper with more power either.
