I bought this pedal to use with my Arturia keylab MKII, for which it works perfectly. I find the quality of the pedal extremely good for that price, and it has linear travel signal profile which I very much appreciate for adding fine grained expression to my sounds.
The only thing I don't like so much about the pedal, is that it has a very tall profile and the travel distance is a bit short. I sit down when playing, and I suspect this pedal is targeted at people who are standing up while playing... But the design is not that bad, and I think its just a matter of getting used to it...
