Right out of the box, I knew that I would like this air conditioner.  It is streamlined and modern looking.  When it was first turned on, I didn't think it was working.  That's how quiet it is.  It cools my whole first floor easily.  I do agree with another reviewer about the rear fins not being protected.  I am keeping this unit in my window year round and it will be exposed to weather and foot traffic.  So that issued should be addressed somehow.
