There is something about prostate stimulation done right that changes the way you think about solo time entirely. This small metal plug delivers that experience with a level of quality and precision you will actually feel. The weight of the aluminum alloy is part of it. Metal conducts vibration differently than silicone or plastic, and once you feel that, you understand why serious guys go this route.Insertion is easy. The tapered teardrop shape handles that for you, and at 1.65 inches insertable length it is sized to wear comfortably for as long as you want. Ten vibration functions give you a real range to work with, not just high and low, so you dial in exactly what your body responds to. The wireless remote works up to 25 feet away, which matters whether you are using it solo or handing control to someone else. Waterproof means the shower is fully on the table. Rechargeable means you are never scrambling for batteries when the mood hits.This is body-safe, nickel-free, nonporous aluminum alloy that is compatible with any lubricant and cleans up fast. If you have been curious about prostate play and want a first real experience with it, or if you already know what you like and want something built to deliver it consistently, this is the straightforward answer.Overall Length: 2.78 inchesInsertable Length: 1.65 inchesCircumference: 3.36 inchesMaterial: Aluminum alloy, nickel free, nonporous, hypoallergenic, body safeFunctions: 10Waterproof: YesPower: RechargeableRemote Range: 25 feetCertifications: RoHS Certified, Prop 65 CompliantColor: Purple
