I bought this as a method of reducing the volume of my snare to play in a small venue rather than for practice. The quality is excellent and whilst I've only had it a short while, it looks made to last. The response is good, if a little rubbery and the tone is pretty good too. Using it with a snare, however, it doesn't give you the same sharpness a normal head would. You do get the crack of the snare wires but you have to put some effort in to get it and it is not as crisp as a normal head.
In terms of volume reduction, this is excellent. The website says it will reduce the volume by up to 80% and whilst I can't verify the exact reduction, it does make a massive difference. I have the 22" bass drum head too and I can really bury the beater without deafening people. Like the 14" head, it has a nice tone.
All in all it's well worth the money whether for practice use or for playing in an environment where you need to play quietly.
