Here's my quick review of the site: It is the worse ever place to buy hash. I set it up to use 1GH.com pool (a rather stable pool and which works on other sites like betarigs etc) and it showed dead for over 12 hrs. When I canceled, I got a partial refund which ate quite a lot of my initial order by way of fees and what not. Finally I had to ask to withdraw my money back, which again is not instantaneous as the site will have you believe. Takes 24 hrs. So quick in taking money but not letting you withdraw.
AVOID!!
