That seems pretty foreign to me. While I would definitely look at something like that (although I've never heard of either of those sites until now, thanks), it seems weird to me that people would assume what some website thinks is "best" is so accurate as to accept their recommendation without doing any research whatsoever and immediately going out to buy that.
Even when I was a kid and had a Consumer Reports subscription I never just bought whatever they said to buy I have always done my own research. It doesn't seem that difficult to me if you have at least a rough idea of what you're looking for in an item and can prioritize those things.
