It was easy to install then remove and put away for the winter.  It is not hideous in the upstairs bedroom and where I installed it it is not visible from any of the seating areas or road outside my house.  But it does not cool my small bedroom with the door closed nearly as much as I had expected.  It puts out cool air but somehow the room never gets really cool, not even if the A/C has been running for hours or overnight.  I have central air in an older home and attic insulation and am only using this to supplement because my central air does not have zones for 2nd floor.  It is disappointing that I am still too warm.
