Do the prices seem right? If it's any cheaper, it's probably fake because even greyhat needs to profit from that - since there's no resellers.
$500 for a 150MH/s X11 mini miner seems to be the market rate, and would seemingly be quite a good deal for a mass producing factory in China. What I am wondering though is how close they are to the Baikal original (are they the same manufacturers?), if it comes with the same software, etc. So hoping that someone here had actually ordered from them before.
