Yea they seem like a bad bet in my book's I saw them post a while back: https://bitcointalk.org/index.php?topic=1454739.msg15795079#msg15795079 .  They say they have been around for 6 year's, and seem to overstate/blur words to make them sound like more then re-seller.  You can see in link above I website has not been around 6 year's.  Even seem to be using LKETC's dragon model name to possibly make people think they were around back then.

Only legit shop's direct are Bitmain's site and BitmainWarranty's site.   No one should even mess with a company like them in my opinion I would love to see some data center pic's from them... as location is hard to believe aswell.
