I bought this to use as part of my Subkick set up. I have a snare stand, with an arm attached, then i have attached the clamp and Subkick. I have only ever used this clamp, and no other,but i can tell that's it's quality. The weight, packaging, and feel is good. It fit my tom arm which was a Millenium ,it measures 7/8 inch.
The only reason i'm knocking a point off is because on the back of the clamp there are two bolts which help grip the arm. The first time i used it one of the bolts slipped through the gap, and my drum dropped out. It is a small design flaw which Yamaha probably didn't think about. It's hard for me to explain the issue, unless you have the clamp in your hands. Having said that once you lock something in place, it will stay there, the above issue is just a minor criticism. I would fully recommend this product. And the price is amazing!!!!
