I haven't come across any complaints about Casino Max or its sister sites. Those sites being Roaring 21 and Cherry Jackpot.
We have a rep whom I've worked with for years. He used to be with the Club World group for a long time. That is until that group got blacklisted by major casino affiliates for some bad practices. That's why our rep left them because he did not want to be associated with a dishonest group. That alone should tell you a lot about the Casino Max group.
