The issue of product satisfaction and representation is one that crops up here fairly often - a guy gets a product that is defective, or fails to perform as advertised or expected - and the buyer seeks help. If he gets assistance that satisfies HIM, all is well - but that same "solution" may well NOT satisfy another customer with differing standards or expectations.
It's just part of living, and buying and selling - and often, both the majority of obviously satisfied buyers, AND the unhappy ones, are both right. It's only when there is evidence of a high percentage of the unhappy customers that the bells start ringing and flags flapping - and even THAT percentage will vary across the spectrum of buyers from any given seller or product.
In any event, as a potential customer for a wide variety of stuff for my own truck, I *DO* pay attention to buyer reports, both good AND bad - and I do value those reports as additional guidance for transactions I myself might get involved in.
After all, if you're traveling across country, and stop for driving directions, and learn there are 2 different roads ahead that will take you to the same destination - but one is rough and winding - but the other is straight and smooth, which one would YOU choose? :-laf:-laf
It's not about "popularity contests for vendors", but more of a scorecard or roadmap for buyers who otherwise must fly blind...
