Currently I am very very unhappy with Black Miner.
I have ordered a sha256 Miner in the Middle of June. Delivery was promised for mid June.
Now their Homepage says early July, but actually it is already August.
But the even scarier thing is that I have sent them numerous emails about the status of my order.
There was no reaction whatsoever. I tried to reach out via skype, same thing.
A statement from black miner would be highly appreciated!
