This is a great non-rigid cock ring for beginners to advanced users. It is stretchy and one size fits all. The material is compatible with water based lube and is well made. It is comfortable once on, however it's not very stretchy so getting it over the boys can be a little struggle without inducing discomfort.

This silicone ring is smooth and doesn't have any texture. It is well made and has no seam. It is very comfortable to have on and there are no smells from it. It's a strong ring so while it does stretch somewhat to get over and around your penis and testicles, it does need some strength to do it.

This is a one size fits all ring. It fits over the penis and testicles very easily and is quite comfortable once on. If you are really big then it may be too tight, but for most guys it's a good fit. The ring looks good also as the finish is nice and smooth.

This is a silicone ring so it cleans up really easy when you are finished. As it is silicone you should only use water based lubes.
