The weights are great, very easy to install and sturdy.
My only complaint is that the tightening screw is a little bit big for a drum key so you have to shift the drum key a bit to tighten or loosen.
Definitely changes the feel of the pedal.
The 25g was a bit too light for me but the 50g weight is just perfect.
I love the 25g weight - the 50 g weight is a bit too heavy for my pedals
Best and heaviest beater weights on the market
I had a hard time controlling the beater swing at higher temps - the heavy (50 gram) beaterweight solved that issue for me!
