There isn't much about this site...Here's what I have found.
I have an account there for few months, the best thing about them is
that sometimes they are slow in removing soccer matches, when most
others have already remove them. If you are a winner your account will
be limited, they offers lots of soccer leagues, tennis and
motorsports. I've heard from people who are having account longer than
me that they never had a problem with their payouts. They have local
shops in Austria, so no worries about their liability. Most of their
members are from Austria and Germany.
