Like many, I had to buy this to cope with a less than ideal positioning of the drum set (or of the neighbor's living room, to speak the truth!). :-)
It works great, the volume is turned down a hell of a lot (maybe too much for some needs), and as a result the cymbal does not sound like a cymbal anymore, rather like a sort of 'ping'; but if that's the only way one can practice, one must make a choice.
It doesn't alter the playing feel too much, which is very good, and it seems to be of high manufacturing quality. I would buy it again if I would need to.
