Used this site for a while and everything's good so far. Prompt bets, decent odds etc.
I also helped this site with an issue they were having a few days ago, all of the reporting went well and they were very professional during the process. Just awaiting the bounty now, will let you when they deliver :-)
Update: All went well! They handled this situation very well and I thank them for being polite during the process. I'll continue to use the site without any hesitations.
