I gave them my money for a couple of foot warmers.  The day I got them, I had to unplug the Christmas tree lights because a breaker popped when they started up and then the same night one of the PSU's cooked itself while I was at work which woke my wife up with that terrible ozonated burning plastic smell.  The next morning I set them up on the kitchen counter where we had a 20A service using an old computer PSU and the paper-clip trick so I could free up the circuit for the Christmas lights.  By this time, she was a little upset with my new hobby but she tolerated it because she loves me
