This is a really well made unit, all the parts are machined accurately so the moving parts won't jam and it always works as it should. The Z-bar stays in the position you set and never sags. It can grip the rims of a drum or the rod of a cymbal stand, however I believe if the claw was re-designed it could attach to the thicker base of a stand, for cymbals, snare, hi-hats etc. This is its limitation. Also, when used this way it can sometimes slip around the rod, even if knurled. A rougher finish would help. But the other similar mounts I have tried also have this problem. This is minor though and the Claw fits onto all sorts of things, such as the tuning lugs of congas, even kick drum legs. You can set it at any reach and angle and it is strong enough to stay there, so long as the place you mount it is strong enough. Despite the minor limitations it's still an extremely useful tool and has been a classic for decades, for good reasons. The current model has been improved. It's the best mount on a snare or tom tom rim for SM57's, M201's or mics of similar size and weight. Great stability and strength, always reliable. I take mine to every gig
