Review: Works perfectly! - Very sturdy (metal, not plastic) and easy to install with clear instructions. We just moved to a state where it gets really cold in the winter and this triple flap doggie door has kept my guys nice and toasty with no cold air leaking in. The magnets work great! We actually installed this in a sliding glass door without any issues, doubled up 3/4 inch plywood in the door frame. We also love that it can be locked from either inside or outside. It works perfectly and we're very happy with our purchase!
Review: Super Duper Dog Door - This is an amazing door. Strong, sturdy and the door is absolutely weather proof. It is in my back door, on the west side of my house, with no overhang, with direct storm impact. The thing I like most about this door is that it has no cheesy interior parts and the metal parts meet in the middle. I had installed another one, highly rated and nearly the same price as this one, a month before. I have had many dog doors and this one is superior to any other I have had and worth the price.

### ⭐⭐⭐⭐⭐ love this door
*by A***C on July 22, 2025*

I hemmed and hawed and researched every door out there prior to buying, i was replacing a dog door tht was by pet safe that sucked, didnt seal and let in tons of air, so the double flap was a real bonus, and let me tell you-this door is AWESOME! The locking panel is a huge bonus if your worried about security, but honesty Ive never used it because my door is a small one and with the flaps and the weather seal around them, I never feel a draft, the doors have a magnent that actually works even though the dogs go in and out all day. Side note I did insulate all around the door with spray foam an sealed around it with caulking on the inside and out but no air gets in or out and no bugs or anything-just the dogs. This door is so worth the money. Its adjustable, and after having it for almost a year, it still looks new and is in great shape. Best money ever spent for a dog item.
