Never experienced buying one from them. What do you mean sounds OK? what don't you just buy items from bitmain itself? A lot of scam sites are out there and don't be another statistics for the scammer. If you are willing to go to mining then I advise you to put out a good amount of investment. Its better to be safe here than lose your money here.

I'm sorry for you lost mate. You are another unsuspecting victim and fall for this scammers. As for the OP, learn the mistakes of this member. At least he gives you a fair warning so stay away from that site. As a advise, just order them to bitmain for your security. Although it will take some time to be delivered, at least you know that you can't be scam by the manufacturer itself.
