been satisfied - polarity can be reversed

For me, the pedal on the parquet floor will not slip, the charge transfer resistance is pleasant, and unlike any other product that I have returned, there are pedaling so far no troublesome mechanical noise, which is the biggest plus for me. I had gelsen the negative evaluation for reversed polarity, and was initially shocked when I realized this with me: "Sustain" was in the case of non-getretenem pedal, and only when stepping out. However, the problem could by googling to solve the issue: The very first accessed website had two solutions, which probably originates from the manufacturer, the first I've forgotten who did not work, the second, the pedal to turn on the keyboard (o. ä.) to operate one has work. Whether I'm so inadvertently reversed in the future once the polarity again, I do not know, that would of course disturbing. Bsher it has not happened to me, but I have not played with it for a long time; 4 stars (instead of 5 because I have nothing else to complain) about only because of cautious restraint.
