This neat little silicone ring from Satisfyer is one of the most powerful mini vibrators we've encountered in a long time. Fully waterproof, rechargeable via USB, and made of soft stretchy silicone, the Satisfyer Vibro Ring comes complete with 10 vibration modes. Like many rings of this style, the vibrating tab can be worn on the underside of the penis for stimulation of the wearer or on the top side to stimulate a partner during penetration play.
