Bought this for a small indoor gigs where volume was a major concern. They brought down the volumes considerably and have eliminated bleeding into the vocal / instrument mics completely. The feel is very close to normal cymbals so it doesn't stifle your playing at all. While the sound fits well in our application, it may not suit your playing style so I recommend borrowing a set from a friend and trying them out before you buy them.I should also mention that you cannot use them with brushes or rutes as it ends up sounding too 'dead'.
