Review on 2020 Models: Highly Efficient Aluminum Dog Door with Rugged Seal Flap - Available in 4 Sizes for Every Dog - Choose Single or Dual Flap Option by Jen Slocum

I installed this door in December (2020) in a side door of my garage that is not used that much. Both doors fell off by March (2021) Yes, exactly 4 months! After disassembling the door I found that each leaf is ONLY held by the top of 3 screws and I mean the TIP of the screw! You are not sandwiched between two pieces of metal that are "squeezed" together by screws, rather each screw just touches the back of the metal and stops. Having spent $180 including tax on this door and 4 months later almost $40 to replace the wings, I would not recommend this door to anyone until the leaf attachment is redesigned. Sorry, but otherwise it would be a great door!
