[Petoasis] Heavy Duty Aluminum Dog Door with Lock,3 Flap Insulated Doggie Doors with Installation Manual,Durable and Rust Resistant, Patent: USD1057087S, (Silvery White, Large for Door)

I have installed several doors for pets across the years/houses, and this door is by far the best we have used yet. The slim aluminum frame is a great upgrade from the bulky plastic doors that extended out on each side of the door in the past.My favorite aspect is that the door flaps can be removed or adjusted. Our dogs had no problems with the new door, but our cat was timid at first. By removing all but one flap we were able to ease her adjustment, and she can now come and go with ease even with the other two flaps in place.Overall great sturdy door that was easy to install.

Good quality doggie door

Love that this has inside and outside door slides so the dog can actually see when it's closed and doesn't bonk his head into it. The three flaps have thus far withstood our heavy winds and remained firmly in place. They say it may be too heavy for a cat to push out, which is a plus for us as we don't want the cat to get out. But so far he hasn't tried it and it's easy-peasy for the dog. Great installation instructions with a template and extra hardware. Very pleased after two weeks with it.

Now the dog lets himself in and out - one less chore for us! Nice quality door, easy to install and works well. The flaps close quite securely so no bugs. Looks nice, doesn't stand out when you view the room.

Having two older dogs I was reluctant to purchase this door but am glad I did. The door was placed into another door that leads to a small room on the back end of our screened porch. It's my departed dad's old ham radio room so we let the dogs use it when not in their kennel. It took them a couple of days to get accustomed to its use and my coaxing, and, yes, even demonstrating! They are experts now. I had it installed by a contractor friend of mine, and he had no problem with the instructions or install.

Fit perfectly and super sturdy. I feel much safer with this dog door than the one I had. I love the locking mechanisms on both sides, great for keeping feral cats etc out.

This door has a few cool features. It is built well and I like the idea of the double flap with middle insulation. It comes with 2 door lock doors, which comes in handy for me when mowing so I can keep the dogs inside without having to go back inside the house to close it. However, I bought it for extreme weather. It fails at this. Any wind over 10mph pushes the flaps open, letting cold air in like if you had the AC on. The magnets need to be much much stronger. I was very disappointed with this feature.

Easy to install. The opening is larger than the extra large I had on a door from Home Depot pre-install. So I would have gone 1Size smaller actual. But we love it and the dog is happy again.
