These nipple clamps didn't work for me because it's typically difficult for me to get my nipples hard enough to wear an item such as this. However, they are pretty, and if you like the design, I would say go for it and get yourself some pretty nipple jewelry.

A clamp is meant to apply pressure and stimulation to a given area. It's meant to stay put unless pulled off or removed purposely. If a clamp releases on it's own for no reason, then it's not really a clamp.

Overall, the decorative aspect of these clamps is a lot better in theory than in practice. That said, though, the clamps feel great and would make an excellent starter set for beginners or a nice addition to an advanced user's complement.
