Tama make unreal products, this is no exception. I use this, along with a boom arm for a 10" Splash cymbal.
Simply, it does not move, at all. I thought that as I was playing it would naturally move away from me as I hit the cymbal, this is not the case at all. The boom arm I am using is larger than normal too which furthers my point.
If you are a heavy hitter then this product is definitely for you or if you need something to sit in a certain way that you know will not move.
So simple, so strong. Excellent product. I very highly recommend it.
