You hear the advice all the time: Before you buy something, especially a big-ticket item, go online and check the user reviews. It makes sense to learn what people who bought a product think about it.
But can these comments be trusted? In most cases they can, but not always. Some are written by manufacturers, retailers or salespeople trying to drum up business. Others are posted by people who are paid to write phony reviews.
