I don't live in the US/UK/Europe so Amazon deliveries are things I pay a lot for and take a while to get to me. So when I buy something, I have to be damn sure I'm going to like it. That's lead to the following strategy: filter reviews to only look at 1-star and 2-star reviews and make sure you can live with it if all the things people say there end up being true. It's served me well so far and no amount of 5* reviews will change my decision to buy or not. Also, I look for things elsewhere, and only go to Amazon for buying, I don't use their search. That helps a lot as well
