I had a guy yesterday on ebay who left a positive feedback.
15 minutes later , he put case against me that item was not as described.
I asked him to post photo and he refused twice. I told him for the last time ebay and I need to see where it was damaged to pursue the claim, because it might be shipping damage.

He then later claim that he dropped the item and he will eat up $120 for his own mistake.

At least he later man up after false claim. At least got < 50% integrity back.
