Hello,
I broke even last week and was able to sell my account with 1.076 GH/s for 3 BTC. So over a time of close to 4 months, I made a profit of around 40 per cent (30 per cent increase in number of BTCs, 10 per cent BTC going up during that time).
Now I am done with it. Still not sure whether they are legit or not, but I do not care anymore. For me it worked just fine and all the nay-sayers were wrong. Period.
