I made the mistake of using this site to buy a linzhi miner- it was a scam.
I have tried to contact them several times and the only time they replied was when I asked them if they could sell me 4 more machines (I asked them from another email, pretending to be a new buyer), but every time i contacted them regarding my undelivered order, they ignored me.
DO NOT ORDER - THESE PEOPLE ARE THIEVES!
Tip for consumers: Don't use this site for nothing
