Here are the reasons I play there as a recreational cash gamer.
1) Steady action up to the equivalent of NL50
2) No mass multitablers and no HUDs = no professionals on the site
3) Possibly tied to #2, the games are very, very beatable
4) Very low rake (2.5%, with 50% "table starter" rakeback for playing at 2-3 handed at 6max or full ring tables). On top of that, you can get rakeback if you play there long enough, and there's no losing rakeback levels (it's cumulative and eternal).
5) Very generous promotions/freerolls. There's a high hand bonus that you don't have to use both cards for, just get quads or better. There's a free roll every hour where the winner gets the quivalentof $1. Their twitter account sends out codes for free chips every few days, and they also run special monthly promotions for freerolls or extra rakeback and the like.
6) Site uses Bitcoins. This means that it doesn't violate UIGEA sinc bitcoins aren't a legal currency. Also, cashing in and out is easy and quick (12 hours max) since they don't have to dodge regulators. Converting to USD via exchanges is only a 1% fee each way (some charge more).
7) Seals also uses a system that I think helps people to play better poker, helping disassociate the chips on the table and their real money value. You play with Seals chips (1000 seals chips = 1 BTC).
Cons:
1) Software is not amazing. The main chat can get annoying since you can't really mute people, just replace what they type with a "*".
2) You have to get the currency (Bitcoins) through a third party. Seals has some resources and FAQs about Bitcoins themselves, it's pretty easy to pick up, but it is a minor inconvenience.
3) Low traffic. It's been picking up as the site gets more notice, but there isn't a wealth of tables at each stake. Currently, I play at their highest regular game at 10/20 (in seals chips), and it's not uncommon for a game to fizzle and die (just this morning I had everyone sit out or leave on two tables after about an hour of play) and not have another one running.
4) Collusion is a possible concern if they play higher/get more traffic. It's not a concern for cash games (most colluders end up being easy money despite collusion), but I'd be concerned if I played tournaments on the site.
5) Few tables run and no HUDs, so if you're used to that, you won't get it here.
6) Nothing runs higher than the equivalent of NL50 with regularity on the site.
All in all, it's a great site for micros players to have fun in and get better or practice for live play. This is really what I'm doing; I'm looking more towards playing live, and this 1-2 tabling at SWC is really good practice. I have an Atlantic City trip in four days where I'm planning on hitting 2/5 at the Borgata... so wish me luck!
