The functions of the three switches on this pedal are set by the device it's plugged into, in my case the Tascam DP 24. It's great for jumping through your recording, punching in and out, etc. Really happy I got it, since it saves me constantly going over to the desk.
The plastic pedal part of the right switch was slightly mis-positioned. It made a click as it rubbed against another part of the device. and the travel was not the same as for the other two switches. it did, however, function as intended. I considered returning it, but I removed the base, twisted the plastic pedal part a little, and put it back together. Now the problem is fixed.
It is not a particularly rugged device, but if treated with respect I don't foresee any other problems arising. Notwithstanding the above mentioned issues, I would certainly buy it again.
