There is a particular kind of intensity that comes from internal vibration combined with the dense, smooth weight of metal against your body. That is what this plug delivers. The solid aluminum alloy construction conducts every vibration differently than silicone does, more direct, more focused, and the tapered teardrop shape means your body accepts it naturally without any effort or awkwardness. This is prostate stimulation done with actual intention behind the design.Once you are comfortable with it seated in place, the wireless remote becomes the whole experience. You have 10 vibration functions to work through, and 25 feet of range means you are not fumbling around trying to reach anything. The plug is fully waterproof, so the shower is absolutely an option. It recharges completely so there are no batteries to think about, and the nonporous aluminum alloy surface means cleanup is fast and thorough. The flared base keeps everything safe and secure no matter what you are doing.At just over two inches of insertable length, the medium size is a genuinely smart place to be for most men who take this seriously but are not looking to push limits. Quality material, real vibration, clean design. If you have been curious about prostate play and want to start with something that does not feel cheap, this is the one to buy.Overall Length: 3.16 inchesInsertable Length: 2.03 inchesCircumference: 4.21 inchesMaterial: Aluminum alloy, nickel free, hypoallergenic, nonporous, body safeVibration Functions: 10Remote Range: 25 feetPower: RechargeableWaterproof: YesLube Compatible: All lubricant typesCertifications: RoHS Certified, Prop 65 CompliantColor: Purple
