Great adjustability means that it will accommodate probably any microphone likely to be used on drums. Clips on to the drum hoop very easily but securely, and is very easy to remove and re-position as necessary. The gooseneck bar is a tight fit in its clamp, which makes it s bit trickier to raise the bar up and down, but don't let this put you off. It's a nice design.
I've marked it down one star for quality because the plastic does feel a little flimsy, which may (and I stress "may") be an issue after a lot of mounting/de-mounting. For me, however, this isn't an issue as I'm using it on a drum kit that never leaves the house.
Overall, great product.
