Overall I consider this a good product. I agree with other reviewers that you will want to buy extra weatherstripping to use for the gap between your slider and the panel, though it’s not that big a deal. The flap works and usually catches properly. My main issue is I haven’t been able to get my cat to use the door on her own. She only goes out when I hold the flap open for her. She is 15 years old, so it is probably just harder to train such an old cat.

Unfortunately, sizing is off. Although the lg door says it accommodates Setters Poodles and Greyhounds I can assure you it does not…

Our Westie loves to go in and out at will! This was easy to install. We added some extra weather stripping just as a bonus. Really a great solution!

My dogs love the freedom of going outside whenever they want. The door fits perfectly in the slider and seems to keep the cold air outside.

This was a game changer. Works great and would recommend.

This pet door is wonderful. It fits well and my little Yorkie loves it.

Great device, works well, fit perfectly, our animals LOVE IT.

Sent wrong size again

This door is easy to remove daily or leave permanently. It is a game changer and allows. My pets to have freedom that they need.

This is a great pet door. It's substantial, easy to install and remove, and looks as good as a pet door can look. I especially like the spring-loaded top panel, which allows me to secure the door without permanently installing it. Because I live in Minnesota, there will be months where I can't use it, so the easy installation and un-installation is a great feature. Worth every penny.

Easy to install, fit great. Took longer to get out of the box, than to install it.

Not as described on the website. I specifically picked this one for the hardware that was supposed to allow me to lock the sliding glass door to the pet patio door. Instructions were placed in the wrong order. It had me lock the height into place with screws before Installing brackets in the sliding glass door frame, making it almost impossible to slide the door back into place over top of the brackets. Top of pet patio door was already bent upon receipt. Does not install onto every sliding glass door well. My sliding glass door does not have a track at the top, so if it wasn't for the bracket weakly holding it into place with one maybe 1/4-1-2 inch screw, the patio door would slide back and forth on the top of the frame. With the bracket in place it does not sit flush with the slider door and the bottom bracket is too wide to be flush with the door because the track limits where it can sit. So the bottom bracket has a gap between itself and the door it screws in to. It also does not sit flush with the door jamb and I can see light through to the outside. The website states that it comes with hardware to lock your sliding glass door to your pet patio door but it does not. It comes only with a lock that can be installed against the stationary part of your slider to keep your sliding glass door from sliding open or closed. Unfortunately that is not the right size either and does not reach from the sliding glass door to the stationary part of my slider. So I got done installing it only to find out that I could not secure my sliding glass door at all. I then had to quickly find something approximately 24 inches in length to temporarily secure the door so that I could go to sleep that night. Not at all what I expected and I do not feel like it will keep out intruders or insects. Still trying to find a fix to make it safe enough to leave it in place.

With slider installed on door track, unable to lock sliding door. Have to place PVC pipe in the track to prevent it being opened. Company's solution for a lock is subpar. Wish dog door fit in the track of the screen, then I could still close and lock it.

This is one of the best purchases I have made. It is installed in the sliding glass doors in the sunroom. I had it installed for me and the installer was impressed with the pet door. There is a slight gap between the sliding door and the pet door, but that is because the sliding door is not straight. I have no complaint about that because it is an improvement over leaving the sliding door open or constantly having to open the sliding door for my dog to go out. Although I have a small dog, I purchased the extra large to accommodate larger visiting dogs. Training dogs to use the pet door takes time, especially if the dog has never used a dog door before. It took about a week before my neighbor's 12 year old dog felt comfortable using the new door. It has worked so well, my neighbor is getting a pet door for the sliding doors at her house.

It did fit lengthwise but could not use the brackets to secure the fit on my frame. The top spring fit piece is what holds this unit place with using backer rod foam I had on hand which I put on one side of unit(wall side) to keep centered on track. My dogs do love it after about three days of learning how to go in and out of the dog door!

This couldn't come fast enough. We have 3 dogs always wanting to go in and out. We visited a friends recently and they had this door. Since we have purchased no more constant up and downs with letting the pups out. Great quality

Easy to install. Dogs love it and so do I. Makes life easier !!

Two of the interior springs broke/fell out/became dislodged at both the top and bottom of the door after only 2 years of regular use - door is now useless.

Product was as described. Easy install. I and my dogs are so happy they have unlimited access to the back yard.

And a slight 5 mile an hour breeze blows the door open with ease. The sweep only lasted a day before the glue died leaving yet more gaps on the backside, that was AFTER adding more weatherstripping.

I’ve used your regular dog doors for over a decade and loved them. I specifically bought your patio dog door because of those experiences. I was really disappointed. - Opening up the package, the rubber window seal was just loosey goosey in the box, completely unraveled with no bag. This kinked the middle. I was still able to install it to the door. 24 hours later, the rubber is lying on the floor. The adhesive strip was still on the door, so it wasn’t an install problem. Your rubber peeled away from Your pre-installed glue strip. Then I had to peel that glue off and use a solvent to clean up the mess. This is a material incompatibility problem. - The instructions for install aren’t clear. Bad verbiage and poor pictures. More pictures/diagrams would be highly recommended for all aspects. A UX designer would have fixed this. - Once I got the door in the frame, I realized there’s a visible gap between the sliding door and the panel. You offered no weatherproofing. When I went to your YouTube channel about the install, just in case I messed up (I didn't, again, poor instructions), YOUR video also shows a sizable gap with light coming through. There are several comments asking about this. Your replies basically say: sorry, go buy some weather stripping. - The lock mechanism is a joke. This essentially renders the sliding aspect of a sliding door useless. In order to open the door, you have to bend over and pull a pin out. So much for usability and accessibility. Didn’t you do user-testing? - Even with your lock, there is no pressure to hold the door tight against the dog panel. I have to use the broomstick method, also recommended by other disappointed users in the comments. Yo… what happened here?

It fits perfectly and still allows enough walk through. Took my little boy a minute to figure it out but he did and what a plus for us. He has a door bell that he rang every 15 minutes. Drove us crazy, now he just goes out when he wants to. Love it.

The sliding glass door insert is alright, but whenever we their is winds, the flap keeps blowing open letting heat and AC out. Stronger magnets should be used to avoid this issue. Would make the door more energy efficient and save customers money from heat and AC loss. I have the extra large door.

Disappointing. Cheap weather stripping fell off 24 hours after being applied. Tough install. The panel did not fit without removing all hardware and locking mechanisms from my slider. The gaps were so big I had to go buy good thick foam weatherproofing. The dog door itself has big gaps and does not fit properly. I followed directions to loosen screws and readjust but the panel needed to be a quarter inch bigger on the sides. I needed something ASAP and it was very cheap because of all my bonuses, so I'm making it work for now for my Boston puppy. Would not hold with a larger dog. Also be prepared to not be able to use the door because the opening is so slim.

This sliding door insert is awesome! Allows our 74 lb large dog the freedom to come & go on his own. We rent, so couldn’t put in a permanent doggie door. This insert snaps into the upper & lower tracks of the sliding door frame and stays there. You just pull the sliding door up to the insert and it appears as it was always there. There’s a magnetic strip at the bottom of the flap to keep it closed when not in use. Great buy!

I purchased this to replace an old Petsafe/Johnson pet door that I could no longer get replacement flaps to fit. I was hoping that it would fit the same as the old door, but it is narrower so required me to move locks and alarm sensor. I have yet to decide if the flap works as well as the old 2 part flaps. I have noticed that the magnet doesn't always catch so am wondering how it will be when winter sets in. Other than these personal concerns, I am sure it would be a great door for a first timer. I have 11 cats that use this door many times a day so it get a work out!

We needed a dog door for our Doberman Zahara to be able to go in and out during the day and had no place to put a conventional one. Our only logical exit was the Sliding Glass Door or cutting a hole in the wall out to the back porch and we weren’t doing that. We are so glad we found this removable panel that fits perfectly into the sliding glass door opening. It’s not a perfect seal but has very little open area between the door and the panel. It’s very easy to put in just lift the spring top in top and bottom grooves and slide as far to the door frame as possible and shut the door up next to the panel. Zahara loves it!!!

Great product at a good price. This is my second one gave it as a housewarming/wedding gift. Everyone is very pleased with the quality. Will buy again.

Works great!! Easy install for sure. Saves money just gotta get onebof my dogs to use it. Still little timid
