Just purchased a new BK-B from Asicminermarket and got a POS used brick. It was all beat up and even spots where they were painting on it. Never started and now I have a $1200 brick. Yang from Asicminermarket refused to replace or refund. I also found out he stole $40k in advertising revenue from a friend of mine. When pressed for the money he owed he threaten with Cyber Mafia. BEWARE
