Review: Only good for wide doors - Good quality but only good for wide patio doors. Otherwise you have to take it out every time you want to go out your self.
Review: Easy to install. Does the job as a cat door or AC panel. - Used this for patio door to make a tunnel leading to outdoor enclosed litter box. Was easy to install. The only trouble is I couldn't get the foam weather panels delivered to a Canadian address. I used plastic sheets to block the wind coming in through the screens. Worked well enough. In the end it can also be used to vent my portable AC. Definitely pricey but I had no other options.

### ⭐⭐⭐ Only good for wide doors

Good quality but only good for wide patio doors. Otherwise you have to take it out every time you want to go out your self.

### ⭐⭐⭐⭐⭐ Very Happy
*by U***N on 6 April 2024*

If I’m completely honest it’s probably a 3 out 5 star product in terms of quality. So why give it 5 star?? Because my balcony door is not a standard size. Apparently there are two standard sizes of patio doors that most of pet companies make and neither has the right height range. My balcony is 84 inches tall for reference. I was hesitant to get this because what I really wanted was one with the glass, but I searched high and low and unless I wanted to pay big bucks for a custom fitted one, the was virtually my only option. So I bought it along with some plexiglass and some weather proofing strips. The door has the grooves that plexiglass can slide in. The plexiglass came in a roll, and I cut it to size but it wouldn’t lay flat and would pop out of the grooves which is why you can see some black duct tape, but this is my fault for purchasing the wrong type of plexiglass not an issue with the patio door. Anyway I was satisfied with the end result. We got it at the beginning of January and it blocked most of the cold air and we still stayed warm. Still doing well and I gotta say I’m super happy I ended up getting. I’m glad it’s even available considering I had no other options. So the extra stars are for 1 for making a product that fits my balcony door, 2 for being super affordable compared to other patio doors and 3 for keeping my dog and cat super happy as they can people watch whenever they feel like it without having to wait for me to open the balcony door. Edit: For reference my dog is about 55 lb, mixed shepherd breed. Hates motorcycles so he runs through the flap door at full speed whenever he hears one and the patio door has not budged.
