First off, i think you're doing exactly the right thing to list flaws & show photos etc

When it comes to feedback though, I have a theory. My theory is there are some people out there who know what they are buying has a fault or whatever and are content to buy it like that but it is as if their feedback is rating the product itself, not the ad, not the description ie what they are saying is-this product is okay but it has some faults, it isn't perfect.

They see this as an honest description of their product. I've seen this time and again with some feedback, almost like they are echoing back some of the original description.

As long as it isn't a neg I wouldn't worry. It's the ones who make it a red dot as well who take it too far-then i would be ringing ebay to see if it could be removed.
