This air conditioner was a ridiculously good buy @ 295 bucks.  I give the unit five star because it has a remote, is just under the SEER to be "energy star", and is a well built unit that comes with a support stand. My house is a 1500 sq ft A-frame, and I cool the entire (ENTIRE) house with this one unit in the upstairs bedroom leaving the door open. The high setting blows so hard it circulates down to the first floor. totally bought me time on trying to budget a mitsubishi mini split unit that will cost a couple grand.

-my electric bill has had no major increase running this.
-my only gripe in the fitment kit was about 3 inches short in my casement window. After raising the unit up 3 inches, it was difficult to seal around the unit since the design was to be sitting flush on the slider/casement ledge.
-This unit is pretty heavy! make sure to have a helped setting it in the window.
