Read reviews of site - the authentic ones are not good. The ones praising it sure have the feel of being fake - there are sites where you can get paid for writing good reviews for a company! You google and see what you think. After I left the site and was doing something else, I get a popup asking me if I needed help or if i wanted to write a review. I had not left my name, email or anything else (except I presume cookies) at the site.
