I installed the Eillion Large Dog Door on my exterior door last month, and so far it’s been excellent in every way. Built with a solid aluminum frame (no flimsy plastic here!), this door feels rock-solid and built for the long haul. ✅ What impressed me: Top-notch insulation: The triple-flap design with a center thermal layer and magnetic seals keeps out drafts, wind, and heat even in extreme weather. Energy efficiency is noticeably better than my old door. I live in Oklahoma and we are in the midst of the hot Oklahoma summer - this door is much more efficient than previous ones. Sturdy for multiple dogs: I have 3 dogs and they will run out this door at full speed (cuz squirrels are trying to take over our yard!) - the frame doesn't flex or wobble—even after the constant in and out use of my energetic dogs. Easy DIY install: Was able to install in under an house. Extra security: The metal closing panel with lock gives peace of mind when we’re out—excellent for safety and convenience. Installation doesn’t include external sealant or flashing, so I added my own weatherproofing to get the perfect tight seal. Final Verdict: If you’re looking for a big-pet-capable, weather-resistant, energy-efficient dog door—this is it. The metal build, insulated flap system, and sturdy lock make it go well beyond cheaper plastic alternatives. Worth every penny and exactly as solid and practical as advertised. Highly recommend to any pet owner who wants a reliable, high-quality solution for indoor-outdoor access.

This is one of the best insulated metal dog doors available — and I’ve tried several. The all-metal construction is solid, heavy-duty, and clearly built to withstand years of daily use. No flex, no rattling, just a rock-solid frame that holds up even with large, active dogs. The three-flap design is the real highlight. The center thermal flap provides excellent insulation, keeping out cold drafts and extreme heat. It’s ideal for year-round use and noticeably reduces energy loss. The magnetic closures work great, snapping back into place cleanly after every pass-through. Install was quick and smooth — under an hour with basic tools. Everything lined up cleanly and the instructions were easy to follow. Small heads-up: while the build is excellent, it didn’t include external weatherproofing sealant or flashing, so I had to purchase that separately to ensure a perfect weather-tight fit. Not a dealbreaker, just something to plan for. Also, if your dog’s a chewer, I highly recommend spraying the flaps with a safe anti-bite spray to prevent wear — especially during teething. Overall, this is a top-tier thermal dog door with metal construction, energy-efficient flaps, easy DIY install, and long-term durability. Worth every penny.

Good dog door. I like that it has two flaps but in heavy wind it does fold and let in cold wind. Overall it was easy to install and like the metal door cover with Lock. I put the metal door screen in and lock it before going on vacation. I don't have to worry about person or animals trying to inter through the dog door for security.

I have 2 dogs that use this all day long. I bought the large one and both my 70 lb lab and my 35 lb smaller dog use it fine. The insulated panel helps with weather. Great purchase and they have great customer service.

Update: it’s $31 (with shipping) per flap to replace the flaps. That’s crazy. Especially if you need to replace both. That’s more than half the cost of the whole thing including the frame. I recommend looks for another dog door with more reasonable replacement parts. I bought this dog door in February and it seemed to be holding up well. Install was simple and the dogs got used to it pretty quickly. It has only been 5 months and the flaps are tearing off. I have reached out to the company through Amazon and they told me to reach out to some weird customer service email that is on the instruction manual. I have yet to hear back and it’s been days. Looks like I am going to have to buy another door in whole just to replace the flaps. Save your money and go with something that has easier to get replacement parts. As a dog owner that has had dog doors for years the doors/flaps need to usually be changed once a year. They do not have a replacement you can buy nor can you easily get ahold of anyone to get the parts you need.

Great product, great design. I bought this to replace my previous door. It was a popular brand with a plastic frame. My dogs destroyed the plastic frame when they were locked outside and wanted to get in. This door has a metal frame and a metal flap cover that can be applied to the inside or the outside. This door should hold up to my dogs' protests to being locked out. It seems very sturdy and well-built and was easy to install. I will update if it doesn't hold up, but for now, I'm very happy with it.

Supplied steel screws were not long enough for my door (which to my knowledge isn't thicker than normal). I had to use the plastic screws which are much longer. Also, the holes which I used the template to locate did not line up with one side of the dog door. I had to drill different holes just using the actual door and not the template. I was installing two dog doors and the other was from Baboni and it was much easier to install. I wouldn't recommend this door.

This is a great product and the customer service is very good with helping get replacement parts. I've had this for over a year with 3 dogs. Installation was pretty easy if you're handy. The dogs love it.
