Was pleasantly surprised about the cooling power of this a/c unit.  Love the fact that I can control this from my smart phone as my husband and room mate both have a habit of trying to make ice cubes in the living room lol.  They turn the a/c on and crank it to make it ssoo coolldd.... I try to keep the electric bill down to a dull roar by keeping it at 73.  Not the fault of the unit, though. It works so well!
