I've been using sustain pedals for about 13 years and I gotta say this one is the best one I've used this far. I haven't (yet) had any complain in the four months I've been using it. Often with other sustain pedals of this fashion I used to progressively need to step on them harder, or even open them up and fix them to be responsive again. Highly suggest this one as it's decent priced as well as great quality.
