There is a reason prostate stimulation has a reputation for being the most intense thing a man can experience solo. When you get it right, it is not subtle. The Eclipse gives you a direct line to that sensation, and it lets you build toward it on your own terms without guessing or settling for something too rigid or too basic to actually do the job.Two silicone probe attachments come with the vibrating base, so you choose where you start and when you move up. The flexible design moves with you instead of against you, which matters more than most product descriptions will admit. Twelve vibration functions mean you are not stuck on one setting hoping for the best. You dial it in. The memory chip picks up where you left off last time, so there is no fumbling at the controls when you are already in the moment. Waterproof means the shower is a legitimate option. Rechargeable means two hours of charging gets you up to three hours of use, and it is ready when you are.This is a well-built set from a brand that has been doing this for a long time. If you are serious about prostate exploration and want something that adapts to you rather than the other way around, this is the obvious place to start.Overall Size: 6.25 inches x 3 inchesSmall Attachment: 5 inches x 1.5 inchesLarge Attachment: Not specified beyond set inclusionFunctions: 12 vibration functionsRun Time: Up to 180 minutes (low speed), up to 90 minutes (high speed)Charge Time: 120 minutesPower: USB rechargeableWaterproof: YesMaterial: SiliconeWhat's Included: Vibrating base, 2 interchangeable probe attachments, USB charging cable
