Sure, it could be something I did. I would have felt better about it if they would have wanted to see the thing. Had I beat on it or dropped it or whatever, the evidence would be readily apparent. Because they were only concerned with the purchace date and not what caused the failure ( they didn't ask a single question as to cause), they either already know what the issue is or don't care what the issue is. Either way, I'm disapponted.
I am a wholesaler myself, and have been for many years. I have never encountered a situation where discount or wholesale price reduced warranty, particularly with a repeat customer.
And this damper has the SFI 18.1 sticker on it.
