I bought two of these and, like others here, had to deal with failures just a few weeks into use. There is a ceramic thermistor (I think) inside that literally burned up and fell apart. The component heated up red hot even when it was plugged into A/C with no load on it. And in any case, my power requirements were only about 50% of the rated output. Junk.
