This beater works. It's nothing fancy and it probably won't last you a lifetime if you're a very enthusiastic drummer, but then again - if you play double pedal, you're probably looking for a different shape anyway. The large felty surface tickles the perfect amount of low end out of my 20" Ludwig Classic Maple. However, it's much harder than I expected it to be and I do quite like that. Nothing rattles, nothing seems to come off at any second and the tone is great. Maybe I will update in a few months though and see if it is still in one piece.
