Hi guys, I just started mining a few weeks ago and now I want to get some better hardware than the antminer u2 with just 2gh/s .... I found the antminer s1 at a reasonable price from their website but I am not sure if it is legit ( https://www.bitmaintech.com/product.htm this is the website I am referring to ) Has anyone bought items from here before ? Is a scam or legit ?

Cheers
