If you've ever wondered how hard it can be to not make a moon joke when talking (fine, writing!) about a toy for your butt called the Eclipse, the answer is VERY. We'll push through though, and just say that the Rechargeable Roller Ball Probe might eclipse some of the other anal toys in your collection.Aside from a curvy shape that targets the p-spot and other inner pleasure places with ease, the Roller Ball features an over-sized vibrating base that stimulates the super-sensitive perineum while inner massage is in session. Oh, and of course, we need to talk about the unique mobile roller-ball swirling with prostate tickling precision at the tip!Gently swollen up top, the Roller Ball Probe instantly stretches, stimulates and targets internal anal sweet spots. Extremely powerful vibration plus synchronized roller ball motion comes courtesy of a dedicated motor placed right at the tip. Vibration and ball rotation is controlled with a push button at the base, which is nice and wide to prevent any too-deep mishaps. USB rechargeable, the Eclipse Rechargeable Roller Ball Probe powers up via an included USB charge cord. 120 minutes of charge time will thrill for up to another 120 minutes.In hypoallergenic silicone, the Roller Ball Probee sanitizes easily and thoroughly for good clean fun. Wash well before and after use using warm soapy water or a favorite toy care fluid/foam. You will, of course, be using lots of lube with this toy, so be sure to choose a good quality water-based formula. Don't be tempted to use silicone lubes- they can break down the material. On that note, it's best to keep this (and any silicone toy) away from other silicone products. Not rated for use in water.
