A cockring that actually does something changes the whole experience. More sensation, a firmer finish, and everything you feel gets dialed up a notch. This one adds vibration to that, and that matters. You are not just lasting longer, you are feeling more the whole way through. That is a real difference, whether this stays solo or becomes something you bring into the mix with a partner.Slip it on and the single vibration setting goes to work immediately. No settings to scroll through, no learning curve. The button cell batteries come included so you are not waiting on anything before you use it. The one inch diameter gives you a snug fit that does what a ring is designed to do, and the vibrating bunny element adds focused stimulation right where it counts. Simple setup, immediate payoff.At this price point and this level of simplicity, there is not much to overthink. You either want more out of your solo time or you do not. If the answer is yes, this is an easy, low-commitment way to find out exactly how much a little vibration changes things. Most men who try one wish they had done it sooner.Product DetailsDiameter: 1 inch (2.54 cm)Vibration Speeds: 1Power: Button cell batteries (included)What's Included: Vibrating Bunny Ring, button cell batteries
