  • Pretty good.
Size: Small
Good product. Pain in the butt to install on steel door, but otherwise it's good.

  • Very nice pet door
Size: Large
This is a well-made and very nice pet door. Installation is tricky because of the trim panels that go between the two parts of the frame that go on either side. First, they need to be trimmed depending on the thickness of the location. Two, they are straight, while the frame is curved on each side at the bottom (though if you're careful you can curve them to match). And they are all too long and need to be trimmed. The instructions are incomplete and end with drilling the holes for the screws that hold the two halves together, but most people should be able to figure it out. My biggest complaint is that the template you're supposed to use to cut the opening is not the right size. I had to do quite a bit of trimming to get everything to fit. That said, once installation is complete, it's a very nice door. ... show more

  • who let the dogs out?
Size: Large
I have purchased several of these. it is a good quality pet door. We have 4 dogs and a cat that ALL use it. they range in size from a 90lb boxer to a 3 lb Chiwawa. its sturdy and it has weather shields. if we want to keep them in/out we place the panel in its slot no enter or exit. we have moved so purchased extra the first purchase was 5 years ago it's still working at that house. it let in less air than our very first doggy door purchased. was from PetSmart and spent 220.00 this cheaper model was a far better value. ... show more

  • Horrible quality - poor fit and gets stuck/jams easily.
Size: Large
My old dog door fit perfectly like a glove and never jammed or got stuck. I only got this because I got a bigger dog and needed a bigger door. This was cheap, but not cheap enough. First of all it's difficult to align both sides properly unlike most half-decent dog door that have two halves that are foolproof and fit together like a glove and lock together with a tounge and grove like design. This one is not like that, the two halves do not lock together, and even if you alight both sides in perfect harmony, the door is prone to getting stuck or jammed. Not only that, the instructions were near useless and don't even tell you what size socket you need for the nut (it's an 8mm, at least that was the size that fit the best). And the hole that the nut goes into is too small for an 8mm socket, or any socket large enough for the nut to fit into, as I have shown in a picture. As a result, it's impossible to tighten the nuts. The only way to do it is to use washers, which are not provided. Luckily I had some extras. And the bolts are too long for most doors of average thickness, so if you want them flush, you need a hacksaw. They're not even the kind that have breakable ends in case you need to shorten them. Overall, I'd give zero stars if I could, and the only reason I haven't returned it yet is because I've already cut the hole in my door and need something there in the meantime. ... show more

  • Looks Good and seems to be well built but not without some problems.
Size: Small
The door works ok, but it is different than a previous brand I have used for years. Instead of a soft plastic flap, this has a hard plastic swinging flap. One of our dogs tries to avoid using it and barks at the regular door for help coming in. Second, I am sorry to say it was much more difficult to install than any of the other three I have installed over the years. Part of the problem is that I did not find any instructions in the box. Also, the solid plastic slide in piece used to lock the door to keep the dog from using it is easy enough to slide in but very difficult to remove. Now that we have used it for some time, the door squeeks as it swings and with many severe thunderstorms the last few months have caused it to stick slightly open allowing wind and some rain to get in. ... show more
