Been wearing mine some days aswell now. First evening I felt the current down there, small zings. It was pleasant, nice mild feeling.
Next couple of days I spent alot of reading on this zinger, many long threads at the PE community and they did some tests with it.
Some people noticed slight effects whereas others did not. What caused this remains unknown, was it the electric current, the zink or just the form of it acting like a traditional cock ring, trapping blood. Who knows. Some people still use it, but most disregarded it after a months usage.
Tom Hubbard, the inventor of this device quitted aswell, stating that the amino acid l-arginine worked just aswell, maybe even better.
Haven’t noticed the zing in my balls/pecker the last couple of days however, just the first nite. I’ll continue using it atleast a month before I make any personal judgement. Sure as hell isn’t comfortable sleeping with, heh.
