E Shock Penis Rings with controller

E-stim 

This electric toy includes two straps, one smaller in diameter to fit around the shaft and another slightly larger to fit behind the testicles. The straps then connect via a wire to the hand held control unit so you can amp up the power from a light tingling sensation to a more throbbing feel. These straps will provide gorgeous electro-stimulation for your pleasure and will work in the same way a cock ring would to prolong ejaculation.

You can use both rings at the same time or use only one ring - why limit your options 

Controller is powered by 1 CR2032 3V battery
