I've never had any problems with PokerStars. In fact they've been quite good to me when I've experienced problems. Once they withdrew my deposit twice which put me overdrawn with my bank and I got charged. I emailed them about this and they gave me an extra $60 in my account for the inconvenience.
I guess theres a good point and a bad one in there lol.

Only other room I play at is Titan who I've never had any problems with at all. I seem to make more there too.

I've played Poker Stars and many other sites. I also have the training program Academy Pro.

Playing online is the same as the training program.It appears to me that poker sites don't use

an RNG {random number generator} they use set program.That would explain why it is so different from real poker.
