This beater, like the regular felt version, is a medium-heavy beater with one surface. I've used the felt version for years before getting this, and honestly? I prefer the felts feeling more. Not to say this is a bad beater, it isn't. It justs makes the rebound feel unnatural, especially if you have a direct drive pedal. No real downsides except subjective ones really, i feel like it's a good buy if you don't mind the rebound changing a bit. The sound produced by the wood surface is clicky, punchy and hits closer to the mid freqs instead of the lower ones like the felt does.
All in all, a good beater! Test it out before you buy it though.
