We've been wanting this particular AC for quite awhile based on some great reviews I've read online.  The dual inverter technology/variable speed compressor is definitely a game changer.  It is by far the quietest portable AC I've ever owned and used and the most feature-packed.  The noise the AC does make is quite easy to live with.  When the air vent is set to oscillate automatically, it creates noise similar to waves ebbing and flowing on a beach--very pleasant for a portable AC.
