I live in Denmark, so the voltage is ~230v, and the voltage selection on the back, is one of those square fuse holder/voltage selectors. It was at 220V, which has worked flawlessly for 2 years, but I guess that might have been a bit on the edge, as I believe voltages have been slowly raised to ~230v. I now have it on the 240V option, but that's after the fault started. (measuring our power here, gives me 228V at 50.02 Hz)
