We can't believe we found a remote control cock ring that's strong at such a great price.  It is not super buzzy and the three nubs allow for better dispersement of vibration. 

Strap on the Rocket cock ring / ball stretcher and blast off into exhilarating sensations. With deep rumbling vibrations, powered by multiple engines, satisfaction is guaranteed.

With 3 speeds and 7 functions, the Rocket is rechargeable & waterproof.
