I got this pedal along with the keyboard bundle. While it responds decently most of the time, it doesn't really feel like the conventional pedals out there, not to mention its unusual shape. Tried it out while arranging something with my midi controller, but throughout the process I wasn't always confident that I was stepping on it right and getting the right response, hence I'll probably not be using it in a live setting anytime soon.
That being said, the pedal has an acceptable build and is light-weight and compact. I like the fact that it has a switch for polarity. In some instances where keyboards go funky and sustain notes when the pedal is not pushed (and don't sustain when you push the pedal), flipping the polarity switch will help solve the problem.
Overall, it's a decent pedal that might need some getting used to for those who want to take it on the go, but for that affordable price it's a good buy.
