We have only had it for a few days but so far i think i like the unit. We do have central ac but trying to save money by running this instead. I trust my wall thermostate more than the display on the unit though. The unit displays 75 but my wall thermostate displays 80 and you can tell the room is not 75 deegrees. It blows string cold air across the room wich i like. The two minor things i dont like are the thermostate display and the door lock on the side where the water tank is at. A peice of tape would hold it closed more secure than the built in plastic latch. So if you have small kids or playful cat etc just know they might be able to open that small side door super easy by just brushing up against it. It had all the parts for the window install and was easy to set up.
