DonnerSustain Pedal for Keyboard, Piano Sustain Pedal Universal Damper Foot Pedal for Digital Piano MIDI Keyboard Electronic Organ Synthesizer (DK-1)

I am a very novice keyboard player and this is my first pedal so my judgment of the product may not be accurate...ProsAdequate cable lengthEasy to press down but does have some resistance which allows you to use it with an acceptable level of accuracy.Stays put. Using on a carpet so take that into consideration. it doesn't move and feels firm even on a soft surface.The signal sent to the device seems to be accurate (minimal latency) which I think is important with a device that doesn't have modulation. It also doesn't have the problem I've had with some on/off devices where at a certain point where it should be on the ON state it would go OFF resulting in unintended output.Built relatively well for a cheap deviceDon't know much music theory but it seems as a beginner it allows me to feign playing more complex melodies with a small amount of keys (25) by sustaining certain sections. This helped me learn to incorporate chords and keys with both hands rather than just playing keys or chords separate.ConsVery cheap materialHinge isn't the smoothestNot had it long though with heavy use I don't imagine it will last as long as the device(s) you're using it for.

Good solid pedal with a nice firm action and good stability. Switch on the side provides for both the standard (Roland) polarity and Yamaha/Korg. It works!

The pedal feels fairly light but sturdy. I have my keyboard on a fairly slippery surface but the pedal stays on the spot. The pedal has a nice weight? when pressing it down and it has an option to change which way the sustain works which I think is pretty cool. (No sustain to sustain by pressing it/always has sustain and press the pedal to stop the sustain)

Very good, no issues

Good but slippery on wooden floors
