I've used them for only about 2 weeks to fund pokerstars. Moved a small amount of money in and out, no problems. Did receive a call from my bank's fraud department. Told me it was because the 2 transactions(micro and regular w/d) looked suspicious. I told them they were legit, and that was that. I also specifically asked if there was a known problem with the vendor, and was told no, not that he was aware. Someone in another thread on EP posted that his bank apporoved the transactions, but knew what they were for, and to not get used to it, so who knows. However, haven't tried the account at any books yet, so can't answer to that.
I'm kind of playing it by ear like everyone else to see how things shake out after this weekend before proceeding with any larger amounts.
