I have purchased 2 of these dog doors and my dog just broke the second of less than 2 years old. The replacement flap costs as much as a new door that may last longer. Does not hold up even though the door itself is very good for extreme weather.

Exact replacement flap for the sturdy door we puchased several years ago. Easy ordering, quick delivery, easy install. Looks brand new and expect another several years of use!

It's great to be able to get parts after 5 years especially when you have a though the wall door and my dogs run though it like a bull built tough.

We've had these doors for quite a while. We have two: one inside the house and one outside attached to the side of the house (the dogs go through a little tunnel, in effect). That's what we call the "air lock." It keeps down any drafts. And wow, they bang throught It! I just gave the re-order info to my spouse so we can replace one of the doors. Our experience has been similar to others: very nice door, but the bottom magnetic strip breaks off, and you have to buy a whole new door. Also, it would be good if it didn't come packaged with those annoying styrofoam peanuts (at least ours came that way).

I bought the extra large door for my mastiffs. It's a decent dog door, but the flap sections don't last. The bottom magnetic strip broke and keeps coming off. The company does not sell a replacement piece. I emailed the company, and my only option is a complete flap replacement, which, for the extra large door, is expensive. I would not recommend this product.
