I bought this beater for a harder, phatter bass drum sound, which it did achieve. But after a couple of months I stopped using it, for a couple of reasons.
Firstly, when I locked the beater face at the desired angle it didn't lock solid enough and the beater face would start to tilt. Secondly, because the beater face is so flat you have to depress the pedal further than with most other beaters. I'm not a fan of this, so I recently bought a tama iron cobra power strike beater which suits my playing much better than the flatter faced beaters.
