Maybe it got dusty during shipping. Lol /s
Anyway what can you expect from Bitmain, they are clearly profit-oriented. Any decently reputable company would let such a thing slide through QA and if one did ever come out, they would have been all over the situation before it got too mainstream. Good luck to all Z9 buyers.
IN the US and the Free world they value that or have to, even most of the Greedily crops in the US do only because of what sane laws we have left that makes them or they wouldn't either and be just as bad as butmian an all but a few get a way with it who have actually killed people and paid there way out of it. an don't think those big crops care they don't if there wasn't laws to force them to be honest they wouldn't be and cover it up so there QA is only there because the law requires it, so no no decently reputable company would care because there are none unless it's small or starting out. the big guys don't give shit one way or the other an only do what they have to watch the news I'm not talking fake news either .
