Umm...Did you even look at the pictures of melted cards and PCBs
Hardly what one would term "non-functioning"
You are misunderstanding Zap.
He's making the distinction between a "refund" vs. a "replacement under warranty".
I don't think Zap is implying at all that the cards are somehow not non-functioning. He's just saying this isn't a "refund" situation. It is a "warranty replacement" situation.
