Unfortunately Amazon reviews, at least in my experience, mean very little any more. There are just too many marketing firms that specialize in messing with them. Anecdotal example: a few months ago I bought an electric shaver that was very inexpensive and had thousands of 5-star reviews. It failed two months later, and when I went to leave the negative review, I found that the product no longer existed, but another identical-looking product with a different name from a different(?) company was the best-reviewed cheap electric shaver.
