never heard of it before but it looks just like a site that has deals listed for sportsbooks
20% is the best deal the have which isnt very high.. yes its cash back but personally if your going to attach a rollover and a bonus I would prefer 100% fp up front at a book. Justbet and Ezstreet both have those.
basically its just a referall site and they give you a portion of their referral money because they get paid when you lose... nothing wrong with it by why root for you to lose yourself.. just feels like bad mojo while betting.
