NEW = in the box, unused, as you would get it from a shop, no exceptions.
MINT = looks LIKE NEW, no marks other than fingerprints, functions like NEW.
EXCELLENT = a couple of VERY light signs of use, maybe a little dust between elements, but nothing visible without a bright light shining through. No brassing. Functions perfectly.
USER = brassing/marks on the body, no deep (deforming) dents or gouges. maybe light faint cleaning marks. Functions very well with no problems.
UGLY = deep gouges in body, scratches that may affect image quality, possibly fungus, functioning. Maybe missing large sections of leatherette.
FOR PARTS/AS-IS = not functioning, serious scratches/dents/marks. ANYTHING from a smoking environment.
If anyone disagrees please let me know but I am SICK AND TIRED of buying things online described as MINT, MINT- or EXCELLENT++ only to find out they're more like USER or even UGLY in some cases. I'm at wits end. I think I'm going to happily pay the premium to buy used items from a store in future. Mods please move if I didn't post it in the right place
