I have just had this message from a buyer :-
( Traditionally, I always give 4 stars, leaving room for the occasional something above and beyond to become a 5 star.)
On receiving this i thought i would do a search and find out what Ebay actually say on there advice page to buyers regarding
the star ratings and found this quote :-
( Detailed seller ratings don’t affect a seller’s overall Feedback score, but we take some of these ratings into account when we evaluate seller performance )
I would guess that anyone who did not know the system and reading the advice pages would think that the star ratings don’t matter much at all.
