I contacted Bitmain and I want to warn all customers,  bitmain this is war. You sent me two bad miners that would have started a fire if I wasn't home and they won't give me new miners as replacement. I am going to report this the the FTC and also enter them on the mail fraud list. I went through all this with another mining company. They are starting a war with the wrong guy. I returned the miners within days but they refuse to accept a return. Only to put a bandaid on these fire traps and send them back to me. complete B.S. and not legal either. I also asked about refunding money and they said the amount would be so low they would give me would be a very low amount and no where near what I paid. Unbelievable....
