“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?

Generally, things sell much quicker on ebay. Although, yes, you can sometimes have to deal with some real turds.....been selling there since 2004 and mostly have had great success. On rare occasions when there is an issue, I make it right to maintain my 100% feedback, which is important. Selling on here? A mixed bag really, limited success. Too many are looking for things other than what I'm selling usually. Oh well...
Everything has been said, but I do agree with geof3. I have never looked at the underside of any piece of equipment that I have bought on Audiogon. Who does that?
Oh yeah, I forgot the buyer who wouldn't buy an item if there wasn't any warranty from the manufacturer.
As I told him, 'Then why are you buying used'?

I always check the bottom of all equipment I purchase used. I don't care about scratches, but I look for major issues. Like some evidence of a spilled liquid or a drop. Scratches on the bottom mean, well, that it has been used.
