I ordered a couple larger sizes than what came with the pump. They worked fine.

Very good product. If you lobe properly they last for a long time.

Good quality. Be careful with the lubricants you use. These disintegrate quickly with silicone lube

Bought 8 of them before I got to my size for the right constriction. Fyi, remember the 30 min. rule and give it fresh blood supply!

Has a good grip on things.

This was a re-order of an item I have used for many years. I received just exactly what I ordered in 3 to 4 days.

Very good

I would buy this item again

I've used these rings for years. I had prostate surgery 11 yrs ago. Without these rings there would be no hope! Natural erections are a thing of the past. The Dr. got the cancer though! Thanks to Erecaid and it's system, it's given me a new life. The new Silicone Rings work better (great erections and erections maintain longer and are easier to remove after sex, than the Osborn Rings or bands. I Just received them, will have to see how they wear! The price is very high, but they work. Will see
