I got this unit a few weeks ago and it just got me through a 4 day heat wave. I love the Wifi feature! I work in construction and it is nice to be able to turn the a/c unit on when I am half way home.. this way, it is nice an cool when I walk in the door!  The unit is very quiet and I know a lot of people want that.. the only problem with that, that I see is, it keeps the fan speed from really having a "hi" setting. Not much difference from low-hi.
