Does what it is supposed to do. The room is cooler but not as cool as expected. the unit is set to 64, but the room is about 75. The amount of BTU purchased was supposed to cool a room around 700 sq. ft. and it's in a 500 sq. ft. room. I would recommend more BTUs to achieve your desired effect. Granted we are in Florida in the middle of summer, I'm sure the unit is working hard.
