Ideal Pet Products Aluminum Pet Patio Door, Adjustable Height 77-5/8" to 80-3/8", 7" x 11-1/4" Flap Size, White

Easy to install and it looks great with the sliding glass door. Would be better if it had a different kind of lock but I just use a cut dowel to secure the sliders. The cat doesn't mind going in and out and I like that if completely see through to the Lanai. Very good quality at a good price!

We LOVE our door. We have a large, German Shepherd Shar Pei mix 60+ lbs and still growing. He loves the freedom and it's super easy to use and install. We added weather stripping to fill in any gaps. It is very sturdy and durable. The glass is thick and easy to see through.

This type of door is very expensive. However, it is a very necessary and useful item that allows your dog or cat to enter or leave the house as they need to. This reduces the possibility of accidents and eliminates the need for a person to let them in/ out if need. The size of the door will fit well in almost any sliding door is relatively easy to install. This door will require that you buy more insulation. The reason is the insulating ability of the included insulation strip is totally inadequate to work well and is impossible to seal, at least it was in my case. You can easily get more insulation on amazon or at a local hardware store if necessary for about $5.00.I have had this door for a short period of time and it really works well it was a slight challenge to teach the dogs to enter and exit on their own. I just used lots of treats. I put their food and water outside after teaching them how to go in/out and that the swinging door wouldn't hurt them. Training will require SMALL BABY steps for them to learn this task. if they are having trouble break the behavior down into the smallest possible steps. For example, just sticking a head inside gets treats and lots of praise. Make a really big deal out of the smallest thing they do correctly. Then build on that success. Eventually, you will have them going in and out on their own. It just takes a little time and persistence. REMEMBER SSSSSSSLLOWW it down you are not in a race. Short training secessions are more effective than long ones. Don’t train longer than 1/2 hr at a time and always end on something they can do successfully, then quit.I didn’t bother with installing the locking feature. My German Shepherd and Pit Bull take backyard security pretty seriously and the lock wouldn’t have fit anyway.Unfortunately, I won’t be able to write many more reviews simply because I simply can’t afford to buy all the items I would like to review. Therefore, this will require me to limit my writing to just a few items as my finances permit. I will still do honest and forthright reviews, just not as many as I would like. I took off a star because of the fore mentionedinsulation issue the door block needs to be more robust so it would prevent breakage and the high price. All of these things are very easy to rectify and the cost for these improvements would negligible.

Very happy with this product. I used to have a similar balcony pet door for my cat, made by Petsafe. However, now I have a puppy that will not fit through, and that one also was not adjustable for my new balcony, so I tried this out. It was more expensive, but the quality was also much better. The flap has a magnetic seal, so that it isn't left open after use. Instead of acrylic or plastic for the window portion, it is glass. The aluminum frame appears durable, and was easy to install. Someone complained about the gap when you close the balcony door on it, however, I don't find this to be a big deal... they provide an insulation strip (which isn't great, but hey, it's free), and the gap is tiny if you adjust it properly (like 1-2mm, not enough for bugs to be a problem). As for the complaint about it making the balcony door unlockable, you will have that problem with any of these patio door pet doors, and it's an easy fix.. just get a balcony door stick lock, or cut a small pc of plywood to fit. Also, I got the large size and the opening is high for my basset hound puppy. I took the other reviewer's advice (the one with corgis), and took out the bottom slat, put it above the door opening pc... all you need is a screwdriver and about 20 min time. My puppy is happily using his gate now, with no problems.UPDATE: Been a few months now, and I'm still really satisfied with this product. I am now using it in conjunction with a Regalo extra wide play yard fence / gate (bent in an arc around the balcony door) and the DoggieLawn/Fresh Patch hydroponic grass products (outside on the balcony, so he can pee and poop on his own terms). Add a Petsafe auto feeder and an iPhone app baby monitor, and he's totally got an independent space while I'm away at work. He has his bedding area and full free access to the outside, where the grass products are, and he can pee and poop to his heart's delight, or just go out and look at trees and birds from the balcony. No accidents lately at all, and he uses the balcony door happily on his own (I still reward him if I see him use the grass boxes for elimination). I would not consider him fully housetrained, as he is just a 12 mo old Basset Hound, but he is well on his way.... pretty good for a breed that is very hard to housetrain. These products (and Nature's Miracle) were lifesavers, because he used to have accidents all the time and escape his homemade enclosure. Now, I go to work worry-free and can watch him on my iPhone from anywhere (the app is called the Cloud Baby Monitor). No more 2 and 3AM trips every 2 hrs at night, down 2 flights of stairs in my condo complex; when I'm away or asleep, my puppy can do his business on his own schedule. Eventually, I am hoping to expand and then get rid of the gated area, once I am satisfied he is trustworthy around the house, and I'm hoping he will just use the balcony door or signal me at the front door with the dog potty bells. Attaching photos of the whole setup (the last is a screenshot of what I see on the baby monitor iPhone app).NEW UPDATE: it is now 15 months since I have bought this… My dog is now a full-grown basset hound. He is still not house-trustworthy and must stay in the enclosure when I leave the house. The enclosure is pretty much like a deluxe dog kennel that allows him access to the balcony potty spot. I still love this dog door – best money I ever spent. In fact, I am probably going to buy a second one to install at my boyfriends townhouse for him, since we go there on the weekends. The flap has gotten a tiny bit discolored over time but still has not gotten permanently bent, and the magnetic closure still works well.
