PetSafeExtreme Weather Pet Door - Insulated Weather-Resistant Dog & Cat Door with Durable Plastic Frame - Maximum Energy-Saving Efficiency - Medium - for Dogs & Cats up to 40 lbs

Installed 6 of these in 3 homes now. They work well. Installation requires some decent skills, a jigsaw with a 4" blade for the door material (not the typical length), drill to make the pilot hole, philips screwdriver, caulking, duct tape, industrial scissors/plastic saw/metal shears/knife (to cut plastic in a straight line), clamp, a vacuum, and some patience. May want to get metal screws to replace plastic ones they provide. A one hour job if you leave the door on the hinges and are doing it alone. I've installed all but one with the door on it's hinges and by myself. Easier if working alone. One or two cuss word project.These work well for 3-4 years and then you need just need to buy a replacement flap. The door is loud with the magnets flipflopping.A few hints:1. There is an inside frame and an outside frame. In between you cut (4) 3" x 1/8" plastic strips that go against the 4 inside edges of the rectangular door cut out hole. You preinstall them on one side of the frame in narrow slots, feed that assembly through, and try to make the 4 sides slide into the small notches on the other side of the frame. This is where the cuss words spill out. It's nearly impossible to make all four bendable stips align in a perfect rectangle as you are messing with the flaps dropping down. The plastic pieces also try to fall off the other side. It's possible with 2 people but still very hard. It will help tremendously to unscrew and remove all flaps (they are replaceable, so they are designed to be removed). Lay the inside frame down on a table, insert the plastic pieces, tape the corners to each other to make it a solid rectangle of plastic, go around and tape the entire perimeter 2x (it'll make sense when you see it), and then tape the plastic rectangle to the inside frame in multiple spots. If you don't, these pieces will flop out or drop off while you are trying to align them in the other side.2. When you insert one side into the door hole (on its hinges), straddle the door, mate the the other frame, and align the bottom of it to get the plastic interior piece in its channel (so the top and sides are tipped out still. If you have a clamp, use it through the cut out to hold the bottom of both sides in both grooves while you line up the sides, and then the top, and manipulate these into their grooves. Have the screws and nuts handy to insert into any one of the aligned holes and hand tighten to secure the plastic. This is the hardest part.3. The next hardest is aligning holes (there are about 12). The plastic screws bend, so you have to push from one side while you look through the holes on the other side to see where the tip is. You need to realign, look for daylight, and watch the screw come through. Repeat for all holes. Again, one clamp allows the assembly to stay together while letting you move it for alignment. Metal screws will be easier.4. Plastic screws are annoying and easy to strip the heads, but they keep you from overtorquing and cracking the plastic frame. If you use a drill and Phillips head, don't tighten all the way and finish with lowest torque or a manual screw driver, using an alternating pattern to tighten, going around a few times.5. If your spouse or buddy will help and not comment and make suggestions, it'll reduce the time by 15 minutes.6. Door on hinge gives you better freedom to lean around, seeing one side and then the other, which probably is done 20 times. On a sawhorse its harder to get up and down trying to align the plastic edges, but you don't have to take off and reinstall the flaps - you just have to reinstall the entire door!7.

Works great, seals the hot/cold out, and the flap functions well! It’s the perfect fit/size for our door! Well made — should last a while with extended use.No more scratches all along the door frame, and ease of access for all of our pets.

Great quality and keeps out weather. We use this for our cats and they love it. It took a few times of us pushing them through it but it worked great after a week or so. The quality is very nice and seems sturdy. The flaps are a little heavy for a cat but they manage to push through. It is great at keeping out harsh weather (our area snows and gets extremely hot). I’ve put my hand near it to see if I can feel the heat or coldness and nothing. It is kind of noisy if you animal runs through it but it’s not obnoxious. I really like this product

I finally got around to replacing our dog/pet door after having a classic medium, single flap door for 15 plus years. The flap was tired, twisted and needed replacing. It was like having a literal hole in the wall, cold air pouring in during winter and hot air in the summer. Add wind to the equation and things get even worse. So let’s just replace the door, completely!This thing, at least for me was not a piece of cake to install because it does not fit the existing opening of my medium classic door, it’s larger! This means there is some cutting to do, two sides and the top. A real pain because it required removing the door from the frame, laying out the hole, keeping it centered, then the whole cutting thing. Not an easy task when you’re working with a hollow core, steel door.Assembling was a pain too. I didn’t like the supplied plastic screws and replaced them with 2-1/2” stainless screws making them easier to install but plan on another set of hands to install them. I cut them flush after the installation. The inside frame was a pain too. I had a hard time keeping it in place while sandwiching the two sides with the center frame and installing the screws. The installation manual is available here on line in the lower portion of the description. It would be worth reviewing to determine if you can manage the job or have a professional do the work for you. Might not have been such a bad idea if I had to do it again. It might be easier too if this is a new installation!As for the door itself, it has 3 flaps consisting of an opaque flap on the interior and exterior with a foam flap in the center. Very nice door but the dark center flap does not allow light to pass through it creating an illusion to the dogs that the door is locked! After years of being able to see light through their door, means it’s good to pass. A dark door means the door is locked! Because the center foam flap keeps light from penetrating, they stare at it in confusion then look at me, like dad, the darn thing is locked, open it! They don’t like it and it is taking some definite work trying to convince/trick them that it’s okay to pass into or out of the door without seeing light! Poor things! I’ll keep trying though and I’m sure they’ll get used to it, but be aware!Even with all this, it is a great door, I would recommend but because of all that I went through I have to give it 4 stars. Maybe I’ll update after the dogs get used to it and after a winters abuse.Update: This door has been installed for a year now and I still cringe about what a pain in the butt it was to install but it's working great. I live in CA so the weather extremes are not too bad. Don't let the manufacturer fool you!! If you have above average carpentry skills and most importantly, the tools to tackle the job then go for it. My skills are above average. If you're installing into an existing hole, there will be cutting! Unless you're a contortionist the door will need to be removed from the hinges. If you have a spouse, send them away for a while because there will be cursing! But wait, you will need a second set of hands for the install. Don't forget to replace the plastic screws with ss steel screws, buying them extra long for trimming. Laying it out is a whole other story, doing it in a steel door is even worse. I digress, my point is, if you don't have the skills, hire a professional to do the install!! You'll be happy you did and so will your spouse. It's a great door and I don't want to discourage the purchase, just buyer beware! On other thing. I have two dogs. One has figured it out really well. The other still doesn't like it and would rather be let out of the slider. She will use it though out of desperation...

Just remodeled my kitchen and it included a new kitchen door with a new kitty cat door. At first my cat was leery of the door because of the dark color. She couldn't see through it. But it is also a blessing because other cats can't see through it either. After I showed her how it would work, she comes and goes easily. I like that it has three layers, it will keep out the weather. We've had a lot of rain recently and it hasn't come inside. The seal is good and size is perfect. My cat and I approve.

Great door, but after about 5 years of heavy use it really does start to fall apart and needs to be replaced.
