Door arrived and I installed it myself within a few minutes. I'm very pleased with it in everyway. Although more expensive, I think I've saved myself money in the long run because the quality of this door - it's mouldings, it's wind block, and it's security have all been so well thought out that I can't see myself needing to replace it for a very long time. The design of this door completely trumps my broken Transcat Dog Door (which lasted 18 months) in every way. Thanks so much.
