Good product, easily installed
My only issue with the pet door concerned my Basset hound using it. My other dog did fine but the Basset insists on standing on the door as she enters. (She does it that way on another pet door she uses.) The edges of the flanges cut into her feet and she stops going through. I cut a board even with the flange height an screwed it in between the flanges making it a smooth surface and she uses it without problems.
