First window AC unit I have purchased.  Still early in the season in Pittsburgh, but am anxious to see how it performs during the hotter days.  So far I am able to cool my whole 2 bedroom top floor apartment (approx. 700sqft) with fans moving the air throughout the house and a dehumidifier in another room.  Very simple controls, but just enough.  I have it set on low cool to keep noise down and temp setting on 8 to keep it comfortable and conserve energy, and I never need to touch the unit.  Small and light enough I was able to install by myself.

I understand this is as simple as they come, the quality my only "con" is the direction it blows air, and the lack of controlling it.  Because of the way the fan moves in the machine, the air tends to blow on an angle coming out the unit, regardless of your setting.  Wouldn't mind the lack of control if it were to blow straight ahead at least.  This is the only reason I gave 4 stars.
