This person is lying. I bought products from "Products4miner.com", which is one of the websites. They honestly sent me the product. Probably the rival of this company and wants to scribble. Please remove this comment.
I don't think you have ordered through products4miner.com yet. How do you slander like that without doing it? I live in England. I went to these people. I talked to them. Very warm and honest people. You are a big liar. Please don't believe what this person says. Just a liar trying to scribble your opponent!
And what you think that people will also believed in your vouch? I mean you account was just created to post here to counter what the OP was saying? I'm not saying that the OP is telling the truth either, but the rule of thumb is, if you wanted to buy Bitmain products, then go to their official website and inquire.
