I'm a keyboard player at a church here in Dublin so as expected I need a reliable sustain pedal to use at home for practice, during rehearsals and during the services. I've owned 2 of this specific model of sustain pedal.
In the beginning I was very pleased. It did exactly what it said on the tin, sustains the note with no problem. However the price gives away a hint, it's not great in the long run. The build quality is impressive to the naked eye however the internals of the sustain pedal don't seem to last.
As I said, I've gone through 2 of these pedals already and the same issue arose. After maybe 3-4 months of consistent use, the pedal was worn out and ceased to function correctly. After purchasing another pedal within about 2 weeks of the first one failing, I began to run into the same issues, premature failure.
Great build quality for sure but it doesn't last. I wouldn't recommend it as a pedal to use in the long run. Maybe at home for practice but you wouldn't want your pedal failing live. It's certainly not worth it.
