4 Stars
It works great!
Why I gave it 4 rather than five stars. It requires drilling holes in the woodwork. My wife said NFW. I had to design a different mounting system. I used 3 lengths of 2x2, two can be seen in the photo. The one on top secures it from going out the window. The one on the bottom supports the weight. The one on the bottom outside the screen frame sets how far in the unit can come. The required screws go into the 2x2s rather than the window frame. The mounting is very stable.The air conditioner works great. It keep the front half (kitchen, family room, dining room, and living room) of the house very comfortable even in 90+ degree weather. It has WiFi that configures with the house system easily. The app works well. It interfaces with Alexa fine. When we forget to set up the temperature when leaving home for a few days, it’s simple to do it from our phones anywhere.In October we will remove it from the window for the winter. It will take both of us to move it.

5.0 out of 5 stars So far I love this thing!
Reviewed in the United States on May 27, 2022
So we recently just purchased this. We just put it in yesterday and we love it! The only thing I could complain about is having to put it together and it took forever to find where to place these panel guides hooks instructions weren't very clear on this. We ended up no using them. So installing it takes a little bit of time. But as for cooling it's great. I downloaded the app and love that too. Being able to turn it off or on and change settings from anywhere is really beneficial to us! A feature we are loving. And I like the look of it. It's not the quietest but not to bad at all especially for its size.
