A lot of times on the internet it's a lot easier to find someone saying "Product X is nothing but shit!" than it is to find someone praising that product. People who buy them expecting them to be good, then get a good product, don't usually post high energy positive reviews, but people who are expecting a good product and get a bad one (whether it be a bad product or just a lemon set of brake rotors) get really pissed and jump on the internet to write reviews on every board they're a member of. I've seen it several times before. The internet can be a valuable tool for research, but sometimes you just have to take things with a grain of salt.
