Product review (1 stars): Flimsy Product / Arrived Damaged / No Seller Follow-up
The product was shipped in a flexible mailing envelope with USPS and the postal delivery worker bent the package to fit in the mailbox.  This caused the metal perimeter to kink in several spots and because of this, the vent filter did not seat properly.  The seller was contacted and offered to ship a replacement immediately, but no replacement was ever shipped and I have not heard from him again.

The product was very flimsy to begin with and didn't come close to the quality of an original.

A complete loss and not worth my time to continue pestering the seller.  Beware.
