This is a very sturdy piece of equipment. It will benefit from a tiny bit of Ballistol oil along the sides where the clamp slides and along the threads of the screw. In addition to using it as a ball clamp, it can also do some amazing stuff as a cock torture device. You can out your cock in it and clamp it down at the base near your balls...a little bit of pain and a lot of swelling--the good kind. My master used a MEO pin wheel on it and it was almost too much; hypersensitive I guess. Anyway you can masturbate with the lower 1/4 of your cock clamped flat in this beauty, and if it's a good strong orgasm then when you release the clamp the cum will literally pour out of your cock.
Whether you’re inflicting the torment on yourself or being punished by your owner, this dastardly device was designed to deliver an a unique array of sensation that will take you to new heights of ecstasy.
