No, I don't and I never have yet. But yes, I think leaving one would be very helpful, which I was not able to think before reading this thread. Before, I think that it's just a waste of time. But if there were not they, then it would have been more difficult for me to choose a product. So, next time I will be considering and hope that other people will reciprocate.
Not really. I only leave a product review if I've found it is either exceptionally good, or exceptionally bad. I think this is common with a lot of other people. Of course on Amazon and eBay I will leave a review regardless but otherwise, not very often.
I don't generally leave reviews, unless I got something above and beyond the expected service. I'm stingy with my review stars, and after leaving a 4/5 on ebay and getting harassed about it, I decided to stop reviewing altogether.
