It is very difficult to review the backers of any poker room. Most of the owners are very well hidden do to the gambling laws, tthey do not want to get arrested.
I would recommend trying a site if it is new without majing a deposit. Give the sites support and cashier a couple emails just general questions see what their response time is and how they do handle the questions.
