Well it's been 6 months on GigaHash and seems to be doing OK till now. Payouts are comparable to Genesis Mining.
Of course there are days when the site's offline and other days when they skip payment but they do certainly make up for it in the next couple of days with typical East European efficiency

I have now upped my hashrate to 1TH/s which represents an investment of ~ US$ 370 (paid in INR almost 1/2 of my monthly salary

).
On paper it's a lifetime contract but let's see where they are 6 months later.
Till then fingers crossed and Lord save the Bulgarians!
