After seeing the prices of individual beats in stores, I had a hard time spending $20-$30 a beat. As soon as I saw the reviews that suggested they were more than enough, I decided to give it a try. I've only used coupes so far. However, they coped easily with concrete and tried to break through the stone for about an hour. There was almost no damage to the top and there was no sign of fading. Just because I've gone through a project and know they're reusable makes them more than worth the price.
