The Portable GE Air Conditioner works amazingly well. It keeps me so cool. In our home this is perfect because my family likes to keep the house warm and I don't. So in my room I use this to keep me cool all the time. It was. Very easy to setup in my window as well. It has 3 functions. It can air condition, be used as a fan and a dehumidifier. I would definitely recommend this to anyone in need of a portable ac or anyone without.
