So far have used it as a microphone for my high hat.  Captures a nice crisp sound, just what you want from a high hat.  Now occasionally on closing the high hat, there's a little bit of a thud, but I believe this is more from external factors (i.e. hollow floor, positioning of mic in relation to the edge of the high hats), not from the mic itself.  Another thing is it's plenty sensitive, as it picks up noise from the high hat when I lift my foot to open it all the way, the sudden stop when it opens creates a faint ring.
