The results produced by Adonis Rings are proven by how long they have been on the market. Men have been buying & using these with tremendous success for over six years. Use one ring at the base of the penis to keep you rock hard & randy far longer than you expect. If you want an even longer experience; try one at the base of your penis & another around your testicles. Most men say that one helps enough; but others have been adventurous & tried three at a time!
