I bought this unit to cool my master bedroom, as it is the hottest part of the house. I have tested this unit in the middle of the day with the blinds open and it really does a great job of cooling down the room. It is a little loud, but if noise doesn’t bother you then its fine. If I had to complain about anything, I just wish the app was more interactive and/or was compatible with samsung smart things so that I could control it from there as well.
