I got a sad story for you.
There used to be this company, Butterfly Labs, they were going to come out with the first ASIC miner and make GPUs obsolete...
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

I only got one, I was working out of state when it arrived. My lady got it set up, configured and on the pool within 4 hours after it hit the doorstep. We made the USD back finally...the BTC, not so much...
Mine doesn't know how to use/move/find our Bitcoins so she has to stick around and keep me healthy.
