I know the owner Adam Anhang personally and he is a great guy. They are very niche oriented and can produce very good revenues if your traffic is adult oriented and heavily weighted towards males.
I put them up last summer for several months and did pick up players and income, I didnt earn huge money but was satisfied with them. When they moved to income access I decided to reduce their exposure as I was annoyed I had to go back and change all links. I also felt they were limited because they didnt have slots or Video Poker.
In summary, they are a decent group if you
a) Have lost of adult make traffic
Have sites which specialize in table games like Blackjack, baccarat or Roulette
