I bought this product as part of my Yamaha P-125 BK home bundle since it is better and more solid compared with the originally included single sustain pedal. Of course, it also increases the overall performance options. It was very easy to assemble and connect to the piano.
The damper (sustain) pedal on this unit is great, close to the feeling of an acoustic piano. The sostenuto pedal also works well. I only have some minor remarks about the soft pedal, which in my view does not make a very distinct difference, only making the sound very slightly softer when pressed down.
But overall a great addition to my Yamaha P-125.
