I use this drop clutch since four years now and I am very satisfied. It is a very useful tool for playing double bass, while the hi-hat is closed. You just have to hit on it and the top cymbal is falling down. When you drop your foot on the hi-hat-pedal the cymbal got fixed again. An advantage of this drop clutch is that it has no winding at the high of the cymbal, so it causes no key holes. The quality could be a bit better. The rubber got broken some time ago, but I repaired it with a tape and have no problems with it.
