You don't have buyer protection.
Ebay give you 30 days to open a case and return a faulty item.
They have to inform you if there is a product recall.
Once they have informed you, it is between you and the seller.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
