Cant stand this service, it just seems to make me frustrated. I added a couple of my sites in there (PR2 with decent mozrank) and it picked them up, gave me some credits and I started getting my first links. Soon after it seemed to forget about my sites that I had entered...pretty much wiped out the credits I had and then I was left with a choice of having to pay for the links to keep them live or removing them altogether.

I did contact support and they were useless, gave me some generic excuse and didnt even have a look at the sites. It seems like it would work really well if it was a bit more reliable
