Endura Flap Pet Door for Vinyl Sliding Glass Doors | Dual-Flap Extreme Weather Design | Insulated, Energy-Efficient Dog Door with Locking Security | White, XL Flap, 77.25"-80.25" Slider Height

I live in Michigan it can get pretty cold and windy. These flaps have great magnets that hold them in place during harsh winds. There is no leaky wind coming in around the door or flaps. This was worth the money; my dogs are so happy they can go in and out when they want and we don't have to worry about when we will be home after work.

I wish I had bought this years ago. It’s given my dog more freedom and she’s much less bored. She no longer jumps on the slider at imaginary squirrels and foxes. I gave it 4 stars because it’s not perfect. The glass itself seems well insulated and the plastic flaps are thick. The problem is that there is nothing to secure the slider door to the edge of the pet door insert. I bought a separate metal bar to wedge in between but it’s not ideal and doesn’t lock. The pet door came with a little metal thing to lock the door in place but it didn’t fit on my door track. If the company could come up with a locking or attaching mechanism to the original door, it would be 5 stars. I don’t you can really find much better on the market though.

So first off my wife and I liked that this product was rated for severe weather and we live in rural Montana. We bit the bullet and paid $700, give or take a penny, and bought this dog door. Starting off strong it showed up damaged and wouldn't install in the sliding glass door completely or correctly (see first photo). This was probably due to the fact that it was packed in a flimsy cardboard box with absolutely NO foam padding except a thin layer at each corner. Secondly, the width of this door is so massive that it made our sliding glass door unusable. Once it was installed we realized that we were only going to have about 10 inches of opening to get through. This doesn't work for us because the sliding glass door is our main entrance and exit from the house. We will be returning this and going with a different product from a different company.

The quality of this doggie door surpassed our expectations! It was worth the money to have something so well-made. We live in the mountains, so blustery weather is normal, but the weatherstripping provided decent insulation from drafts. Our Siberian Husky ADORES his door to the deck! FYI, we removed a couple of the extra magnets to make the door a little easier to push open- it’s still plenty strong, and it always closes. So pleased with this door...highly recommend!

800 dollars for a pane of glass and a flap? In what galaxy is this worth 800 dollars? Lmaoo

This door is exactly as advertised. It was easy to install and is weather tight. Our Goldendoodles learned to use it quickly. This was a great buy!!
