In my country (belgium), it doesn't just cover manufacturing defects but all instances of "non-conformity", meaning discrepancies between the advertised product and the delivered product. This makes sellers responsible for accurate representation of the product they're selling. One gotcha is that you have to be unaware of the nonconformity at the moment of making the purchase. So manufacturing defects are not covered if they are documented to the buyer ahead of the sale.
