I love the build quality and the engineering behind these pedals. I also like how they've gotten rid of the springs on the outside. However, in the pursuit of speed, what they've done is focused the pedal so much on speed, it does not possess the ability to do anything other than loud and speed. It's absolutely great for that, and for a metal or rock drummer, it serves its purpose as good as any. However, I think it would be completely out of place for anything quieter - because its a short, compression spring instead of a tension spring system, you get increased resistance as you push down on the pedal, which means you counter by playing harder, and in turn, louder.
