When Doc Johnson The O Ring still wins
men who want a single inexpensive round ring. We are not going to talk you out of a listed medical device, a pump-matched tension ring, or a lidocaine spray if that is the mechanism you already chose. This page exists so you do not buy those by accident when a $25–$50 product was the actual question.
Safety
The Mammoth, Dragon and Red Tiger product pages say thirty minutes maximum and never while sleeping. Remove at once on numbness, pain, coldness or a dark colour change.
