We practice karate in the garage so it really helps cool the room when it’s over 100 degrees outside. Putting it together is very easy and you do not need to cut a hole on the wall because it comes with a kit where you can attach it to the window. I like that you can visibly see the set temperature on the front of the unit but the only drawback for us is that the cord is too short! You cannot use an extension either. But other than that, it’s very well made and it serves its purpose. I highly recommend it.
