sending used equipment is so fucked up. don't get me wrong, i get it. but it's still not right. BFL was doing it. avalon was doing it. now bitmain is doing it. they will all do it to us. it's such a bend over the customer racket. nowhere else would that be acceptable but they get away with it cause everybody wants to be a part of the gold rush. and to add insult to injury they only offer a 3 month warranty after they been mining with it for months.
I'm confused. Did the S1 mine at the advertised speed or not? If the S1 was used but did perform as advertised, I think it's pretty crazy to return it, pay return shipping, and lose out on mining revenue while waiting for a replacement.
