Good balanced weight, the right amount of stiffness to allow articulation without being overly loud. Self noise (the sound of the sticks interacting with each other) is low unless you roll the o rings down all the way, then you get a more brush like quality. Can't speak to longevity as my pair is used about 2 hours a week, but no issues yet with individual sticks breaking. I've had them for about a month. Bought these to play quieter sets while getting more speed and accuracy vs brushes. They truly drop the strike volume by a solid 10-20 dB. I'd buy these again in a heartbeat.
