Wingmat is only ever mentioned by people who work for the company. i.e., posters like you who are brand new and making their first or second post. They keep going into different GMAT forums and asking this same question, again and again. And every time, at least one real forum member points out that they do this (usually shortly after another fake forum member posts a rave review for the product, even though no one else has ever heard about it).

I'd say you gotta give 'em points for trying, but this is truly PATHETIC.
