I've been betting with ComeOn since November 2013.
They are licensed in the EU and hold the highest of
European standards. ComeOn offer a nice signupbonus
(depending on country) and getting started was easy.
My bonus was credited with no fuzz and worked like clockwork. Once registered you'll easily find your bets
and they even offer ComeOn points. The points are awarded for bets placed and even logins. I've used the points to buy reload bonuses, spins and even cash.
