I would agree to check those reviews but nothing beats more about player's experience. Each of the gambling site have their own uniqueness, strengths and weaknesses @op we are just here to give our opinions and experiences but just like littlemouse said some of the users might be biased so there's no actual point not unless you tried the gambling site they are referring.
You're right, just that Little Mouse does have a good point. Many of the recommendations are from those wearing the signatures of casinos themselves.
While there are reviewers that just leave their links in hope of referrals, the two I mentioned above have spent their own money and are more direct when it comes to which casinos are good and bad.
