I bought this air conditioner in early May in preparation for the hot summer expected.  It has exceeded my expectations and more!  I am a teacher who works summers in a hot building and outside.  It is so nice to be able to go home and KNOW that my air conditioner is going to work exactly how I need it to.  it cools my room down significantly.  It has wonderful features such as ECO mode as well as a timer.  I also love that it comes with a clicker for the lazy mornings or nights when I don't feel like getting out of bed to change the temperature or setting.  Highly impressed and am a very happy customer! [This review was collected as part of a promotion.]
