This is fine for the beginner, however, it is not for the advanced. Barely felt a pinch. There is a screw to reduce tension, which I do not think anyone would need. Even putting one clamp on top of the other did not increase the tension much. Slips right off with the smallest tug of the chain.

Increase tension to the point the clamp can hold 2-3 lbs. Plenty of clamps out there with light pressure; however, I cannot find anything with suitable tension for advance play. I prefer a clamp that can hold 4-5 lbs. However, I know not everyone likes that much pressure.

This clamp has barely any tension. Needs a tighter spring for someone more experience in nipple pain.
