I have an over 500 feedback rating but I've had a few poor experiences. The eighty characters in a feedback line are often not enough to explain. Here is the full story of those who screwed me over. My first was a French 'gentleman' who bought an old, cheap lens off me. It left here working but failed soon afterwards. Instead of asking for a refund, which I would have gladly given he just posted a negative feedback. Nasty and stupid.
I have no pix for that one but the more recent experiences?...Click on the image to see the problem.
