I really like this unit but I do admit the price of the unit has my expectations higher. I paid the extra so I could open my window on cooler nights. The unit does not filter water out the back properly it is very loud after it rains. It is installed properly. I also used the extra foam to close in the space between the screen and the unit as well so bugs didn’t fly in. That being said, it’s a nice unit. The quiet mode is very quiet.
