Camera shows wear, but it still takes great photos (I included the test shots that I took today). The only "issue" is that the mode dial can turn forward without pressing the button. It doesn't affect quality of pictures, but I suppose if it got bumped when you are shooting then it might move (I've never had that issue, but need to point it out).
Shutter count is 40,107
I am also selling an 80D; I have loved both of these cameras, and liked having the 2 cameras with me, but I recently switched to mirrorless, so I am selling them both.
