This unit arrived just in time for a brutal heatwave in Georgia a couple of weeks ago.  Installation and set up were straighforward.  It very efficiently cools a 300 sq ft room, my man-cave; I rarely have to set it below 75 for the room to be comfortably cool, with the central air for this story of the house set at 77.  It's not silent, but it's a lot quieter than a conventional window or portable A/C unit with a compressor.  Its design is modern and attractive to boot, and the control panel is intuitive to use and responsive.
