The main reason I got this product was because I usually mount percussion on straight bars from LP clips, or from the tom mount in my side snares.
The issue with that, is that the percussion is totally flat, but by having at least one of these mounts you can use the bar that comes with it for your current mounts to allow your percussion to tilt slightly.
Apart from that, the mount is excellent and sturdy, but maybe a little too expensive for what it is, and that is why I give it 4 stars.
