Ouch sorry to hear that, I was flip flopping back and forth over whether or not to buy 1 of these or wait on Canaan. I ultimately decided to wait on my Canaan order as I am done jumping around beating myself just to get a unit up and mining again.

was this your first one from them, I have been trying to find any info possible in regards to the average failure/DOA rate for these units. Good luck resolving your issues.
