Alot of micro players seem to really like it. I haven't really played all that much on there to be honest & actually just recently added in a few MTT's from there onto my schedule. Play is defintely on the weaker/softer side.
I have a friend who plays the $5 sng's on there & they seem real easy to beat.
As far as the software & graphics, etc. goes.... I don't really like it. Many seem to like the graphics but I find the tables a bit cluttered & distracting. They also are sized a bit differently from the other sites which makes tiling them in with others a bit awkward.
Not sure what the player traffic is like on there (ie. how many tables are open for micro cash... or how long of a wait it is for a 9plyr. SNG... or if they're busy enough that you could easily be playing a handful of them at same time). Also not sure if there are many multi-table SNG's running (smaller sites usually seem to have a hard time filling up the MTT-SNG.. ie. 27plyr. 30plyr, 45's, 90's).
As far as whether it's a good site to play on goes.... I think that'd depend upon what you're looking for in a
poker site. I think that for a newer-'ish' player, playing micro limits, Carbon might be a good place to get started (I'll often hear about newer players having decent results on Carbon where they weren't able to do so on some of the other sites).
