I realize that the website in question is supposed to take user reviews. However, it seems a little strange for anybody to fully trust (or expect) a vendor website to provide unbiased opinions.
Almost all sale persons that I have met will hype whatever they are trying to sell. Most of them will rarely willingly let us in on the negative side of their products/solutions. Considering that the website is probably in the position to want to sell their merchandise, they would favor good "user reviews".
I'd imagine most people will search for information/reviews from various sources. I doubt most stores will start listing "how this product sucks" if they are trying to move inventory.
