The unit is very attractive, though mine arrived with a slight dent in the housing. Installation was fairly easy, though I had to adapt it a bit due to my storm windows. It cools very well, however it does rattle and buzz. I had to tape the filter to the unit to stop vibration noise. I am least satisfied with the way the unit and app communicate. I have deleted and reinstalled it, but the app always registers the room temp as 67 and watts used as 20. There is a long lag between turning the unit on in the app and it actually coming on. I had it set at 68 and when I woke up, the display on the unit read 59--a little too cold.
