Bought this on a recommendation from an A/C expert on window and portable units.  The BTU's for a window unit are NOT the same for a portable....you need more BTU's for a portable to circulate the air.  Combined with investigating decibel levels, ability to cool and my issue with amperage in my apt, this was the best choice.  It unit is incredible with cooling and while not whisper quiet, it is much better than my old LG unit (these portables are never quiet unfortunately).  For what I needed, this was a great choice and having the remote by the bedside to turn off and on, or higher and lower speed is terrific.  Wayfair delivered on time and on schedule.  I am very happy with my purchase.
