“Marks on the underside”


I sold a piece of equipment on eBay and described it as having only slight almost invisible blemishes.
The buyer requested to return it to me because of “marks on the underside.”
I granted the return without delay.
Now I’m having second thoughts.  My question is, do marks on the underside which obviously are not visible when in normal use, count as a valid reason for return?

Not sure I’ve ever even looked at the bottom of a piece of gear... seriously, who does that? I’m with the rest. Not worth the hassle. Buyer pays return shipping, get it back, refund. Be done with it. 
Overstate blemishes and detail them in photos. Let the buyer decide and cover yourself.
Always include Hi Rez pics of every surface (underside incl) & describe every mark accurately.


Yup singintheblues.  Seems obvious to us.
Hi res photos will do with just a reference to each mark - It's not easy to describe a mark accurately.
