The guys at WOL and Bet2Gamble have been trying them and so far there do not appear to be any problems. This is what Casinomeister News said about them last month:
"We chose the final cool casino this week because it is such an unusual...and busy...site. iVegas.com has 35 Flash technology games on a site that also carries a community venue, chatroom, winner's stories, gratis email, an online shopping mall and of course a casino - all with a Las Vegas theme. Plenty to do here! We are told the software is proprietary, and it is not world-beating in quality. Support services are available, and the e-cash routes through a company called G-Cash. There are signups of up to $300 but visitors are urged to read the T&Cs very, very carefully."
