It is keeping 450 sq ft of living space cool and is really quiet. One thing on install, which I did with help of a friend, is if your window depth is right on the limit of a setting, go with the smaller setting. Mine seemed like it should be on 2 but once it was straddling the window ledge the part where the feet would secure against the exterior wall was narrower than the window frame molding. Since the unit hangs below the window sill, it’s the thickness of the wall that matters. The installation video was helpful but not on this issue. I had to go to YouTube to figure out the adjustment needed. My unit is on a higher floor, so a bit more nerve wracking when trying to secure the unit & keep it level. Haven’t bothered setting up WiFi since I don’t use an Alexa like device, so no comment on that aspect. I just love how quiet it is and the options of auto & eco settings. I’m considering getting a smaller version for the bedroom because it’s much quieter than what I have now.
