Playersonly also gets a D+.

All of the sportsbooks in that family get a D+ or worse. AFAIK Visa/MC are the only way to deposit and check by mail is the only cashout method. Players report delays in payouts from 4-6 weeks although now and then I hear a report of 2 weeks. If it takes this long to pay players when will affiliates get paid? I also believe these rooms only accept players from the US per their deal with Sporting Bet when they bought sb.com.
These rooms are on the same network as Cake Poker and Red Star Poker. Both of these rooms accept ePassporte and payout in a day or two. Why not promote these rooms instead of slow paying sportsbooks with more then their fair share of complaints?
If you are not familiar with the network Cake is the main skin. The software is atrocious but they have great promos, many of which they do not deduct from MGR. The game quality is also above average, especially compared to US rooms.
