I don't want to hijack the thread, but just a quick note on a pet peeve of mine: you aren't "biased" by stating an opinion, even if that opinion doesn't take into account all facts (i.e. you used only one of many products and say that one product is very good). Bias means you either have a duty to be objective (as an official, say) and aren't or it means your opinions are offered for a motive unrelated to quality (say, you profit from the sale of something).
Sorry, back to football.
