There is something about prostate stimulation done right that changes what solo time means. The right toy, the right material, the right vibration pattern, and the whole experience shifts. That is what this plug is built to deliver. Smooth, weighted aluminum alloy sits differently than silicone or plastic. You feel the density. You feel it respond to every pulse from the motor in a way that softer materials just cannot match.At 1.65 inches of insertable length, the small size is the right starting point if you are new to this or just prefer something you can wear comfortably for a longer session. The tapered teardrop shape makes insertion straightforward and the flared base keeps everything where it belongs. Ten vibration functions give you real range to work with. The wireless remote reaches 25 feet, which matters more than you might think when your hands are occupied. Everything is waterproof and rechargeable, so the shower is an option and you are never hunting for batteries at the wrong moment.This is body-safe aluminum alloy, nickel free, nonporous, and compatible with any lubricant you already use. Viben built this to a real standard and it shows in how it feels. If you have been curious about prostate play and want a quality entry point, this is the obvious place to start.Overall Length: 2.78 inchesInsertable Length: 1.65 inchesCircumference: 3.36 inchesRemote Range: 25 feetFunctions: 10Material: Aluminum alloyWaterproof: YesPower: RechargeableHypoallergenic: YesNonporous: YesNickel Free: YesBody Safe: YesLubricant Compatibility: All lubricantsCertifications: RoHS Certified, Prop 65 Compliant
