I remember them rating Scotch brand VHS tapes as number 1 and I was skeptical as I had never heard a good Scotch audio tape. It turned out that the VHS tapes were so poor that stores closed them out at dirt cheap and stopped selling them altogether.
There have also been other instances as well when they rated something very high which turned out to be crap down the road. I'm sure they get it right sometimes but I don't put much stock in their reviews of anything.
By the same token, if I own a product that they rated very high or number 1, it makes me feel smarter somehow. Apparently, we're kind of like dumb animals and even if we made a bad decision, as long as someone pats us on the back and says "good boy", we feel better.
