Hands down the worst bass drum patch I've ever owned. I have brand new tama speed cobras, and this patch's rough surface has eaten away the felt on the bass drum beaters. Now I'm out 30 bucks for new beaters. So this patch may be cheap, but don't let it's price fool you because it'll end up costing you in the end. get aquarian or remo instead. I've never had a problem with either like I did with the Evans patch.
