excellent, 10/19/14
I live in florida and bought this to keep the air conditioning from escaping. I like the fact there are three flaps and it closes tightly to preserve the coolness in the house. I woukd highly recommend this product.

Door worked fine except for the cover, 10/13/14
I reviewed the wimpy cover by itself, so to me this is strictly about the door. The door itself was fine. It seemed to do what it said it could. One of the dogs living at my house tore up the flaps because the cover couldn't stay on the outside to keep him from getting to it (I will blame the dog for this as well, because the other dog living at my place didn't even try). With that being said, while the flaps got ruined, the dog door stayed in place, even with use of the nylon screws. Using different techniques to keep the dog from trying to bore his way into the house, the dog would try very hard to get in, and through that whole issue, with him literally trying to tear his way in, the dog door didn't move a muscle. So to me the door is fine, its the wimpy cover that needs to be fixed.

Excellent for Michigan Weather, 10/12/14
Since I installed the Large Extreme Weather Door several years ago, it has endured extreme Michigan winters and 4 large dogs. I just now have to replace the insulated panel and one flap. The only reason I gave it four out of five stars is that the plastic snap-on closing panel can easily be removed by my dogs and does not stay on without having something propped up against it. I would love to have a cover/panel for this door that prevents access by my dogs, wildlife and burglars.
