A quick 8 minute video of putting clamp on and how I go about my routine. I am about 60-70 percent erect when I first put clamp on. I don't get the last click cause I clamp for 20 to 25 mins. I wanted to do this short video so guys can see how to attach the clamp. I apologize for the noise in the backgorund. I hope this helps those who are interested. Plus helps if you shave your pubic hair or thin it out so no hair gets in the way of the clamp. Any questions or concerns email clampmaster@proton.me
