One of the better clamps I have used. Very sturdy, and extremely reliable. I used it for a 4 hour practice, and for a 3 hour gig afterwards, and all the clamps held perfectly. There was no need to adjust them, no slippage, and no coming loose.
If you are going to pick up the DR-80 drum rack, then I would really advise picking up a few of these guys!
Amazing quality, at an amazing price!
