Blackarrow still hasn't shipped, they hardly ever communicate and they don't offer refunds.
how are they still a C+?
Exactly, Black Arrow should be downgraded to BFL territory Z-
That would be the only fair grade for this obvious scam outfit that won't refund customers, won't communicate real ship dates, won't offer realistic or fair compensation, forces customers to buy additional PSUs for said compensation, and deliberately deleted any relevant comments from a Whistleblower who was spot on(Phinneaus Gage) on their main thread, so they can continue on with their charade as a "legitimate company".
They executed the "Long Con" to perfection, as they've finally announced that they'll finally ship at the end of July. If they do ship or not these useless miners, doesn't matter, only Minersource customers were able to get refunds. BA was able to pocket the rest.
Considering all the millions of dollars they swindled out of customers(Minimum Order Quantity of X-1s: 10 and X-3 ~$6000), 5 month+ delay, multiple multiple difficulty jumps later, the only fair rating for these crooks is a BFL class grade.
I'm sure Dogie will do us all right with his next update. Warn all noobs and prospective buyers of mining equipment, the dangers of ordering from the crooks called Black Arrow Software.
