This is a very easy-to-use cock ring that fits easily over both penis shaft and testicles. Since the material is soft and very stretchy, it is easy to put on either before or after things get hard. It is very comfortable to keep on and does not constrict too much. Since it goes around both the base of the shaft and the testicles, it keeps you rock hard. If you are hairy down there I can see that it may catch and pull hairs; however, I keep myself trimmed, so it's not a problem for me. I love this ring!

The material is great. It is jelly-like and very stretchy. There are no seams that I can detect, and the knobs on the ring provide that extra bit of stimulation to both partners. Since it was so stretchy, it is easy to get on either when you are soft or hard. Just add some lube to help slide it on, and away you go. The material has no odor and cleans up real easy.

This is a one-size-fits-all ring and the material stretches easily. I found that the shaft ring was the perfect fit; however, the ring for the testicles could have been a little tighter. That said, the lower ring really lifted my testicles up and provided extra stimulation that a single ring would not have. The feel of the material is such that it is very comfortable to wear with no tugging of the skin.

I would advise against over-stretching it as this will eventually wear it out, but for normal use I can see this lasting a long time. Other than that, this ring is very easy to maintain. Just clean with soap and water. When finished, keep it in whatever container you see fit. I find that it does not attract lint like some other materials.
