Door is perfect. Heavy duty and seals great

The pet door works flawlessly and the dogs have easily taken to it, even the timid ones. One dog even finds it entertaining to keep running in and out. The pet door has strong magnets along the length of each side of the flap and fully closes every time a dog goes through and withstood some high winds we had last night without blowing open. There is also soft weather stripping along the outside and bottom of the opening to prevent air from leaking through. The wall insert was the perfect depth to fit our exterior wall and is strong aluminum and doesn’t need additional support installed around it to keep it solid. The only draw back is the installation instructions are very basic and need to be more detailed. The wall insert only has instructions on how to assemble it, but not how to mount it to the inside and outside frames, as a matter of fact, it doesn’t physically mount to the frames in anyway, but is held in place by pressure. It would be useful if the door kit included a cutout template for ease of installation, but isn’t needed if you have some basic DIY skills. The pet door itself, I would rate 5 stars, I knocked it down to 4 because some others may need more detailed instructions before feeling confident enough to cut a hole in their wall that’s big enough for a German Shepherd to step through. It will be fairly quick job for your favorite DIY-er, so fire up the grill and the fill the cooler and be ready to reward them for a job well done.
