umm, now that you make me think about it..., you can't even prove that you get a busted bearing (bicycle part, 1 year ago), because what can you photograph when you can't take it apart?
Sealed bearing, I don't even have the equipment to dismantle it from the hub, and it's not even trivial. It was a defective Chorus sealed bearing front hub from 1998, listed as "very good condition", which sure, aesthetically it was exactly like the photo in the eBay listing, too bad it had broken bearings
So, 60+15 S/H euros wasted, another rip-off I got, as eBay closed the case as "that's your business".
At this point, as far as I understand, you just have to pray that the seller doesn't respond, so eBay will refund you automatically.
... maybe
