I should add that although I have only written a handful of Amazon reviews, mine are mostly highly rated because products that have work well for me (or at least met or exceeded my expectations) are almost the only ones I write about. If I ended up on the bad end of a lemon, I would probably write a review about it, but that hasn't happened to me. I would like to think that if I was part of a program where I was sent free stuff to use and review, that I would be honest in the ratings I'd give.
