This clamp is super well build, has quality feel to it right out of the box, is super easy to fix into position and apply slight tweaks afterwards and stays rock solid in place without any slack in any direction!
Using on my Roland vdrums rack (MDS-9) to hold my extra cymbal boom stand and it feels like it is very light for the clamp - it can hold something a lot bigger and heavier!
In comparison, initially I got one of the Roland plastic clamps for the same purpose, which was moving around all the time and finally broke the consecutive time I tightened it yet again so it won't slide. I should have got one of these instead from the starts...
