This is the smallest and neatest wireless vibrating cockring we've seen - just like its' one-use little brother, this stretch silicone ring is small enough to slip into a pocket for a night out but packs a surprising punch - the tight ring will prolong your erection up to four times as it keeps the blood from exiting your erect penis; it also sensitises the head, and creates stunning clitoral stimulation if you wish to share the experience with a lady friend! However, this little chap will never run out. It takes two cheap L1154 cell watch batteries, so you can keep playing as long as you like!
