I had very low expectations for this product, it was cheap, and I just needed an extra sustain pedal for a synthesizer - WOW was I surprised after testing it! It's heavy and rubberized, so it stays put, and the feel of it is very much like a piano. I like it!
It's actually better to use than a similar Yamaha product I have, priced at at least twice of what this pedal costs, and I wouldn't imagine the quality to be much different.
At a price like this, what do you have to lose?
