IIRC 'used' items should only feature cosmetic damage
From t'bay:
Used
An item that has been previously used. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or an item that has been returned to the seller after a period of use. See the seller’s listing for full details and description of any imperfections.
For parts or not working
An item that does not function as intended or is not fully operational. This includes items that are defective in ways that render them difficult to use, items that require service or repair, or items missing essential components. See the seller’s listing for full details.
