Buy this door

I’ve owned this door for 4 years and can say with confidence that buying it was the correct choice. When you look at the different designs out there it’s really the only reasonable choice if you care about energy efficiency. They have that video with the fan on the manufacturers website and I would say that it is every bit as air tight as they advertise. I have a jack russell and a 90 pound pit/boxer mix and they both barrel through it at top speed several times a day. It is showing signs of wear after 4 years of this, but over all it’s held up pretty well. I’ve had to contact the manufacturer twice regarding issues with the door and both times they exceeded my expectations with their service.
