It was 99 degrees outside, with 106 heat index here in Texas. 15 minutes after getting my brand new NewAir Portable Air Conditioner delivered, my entire living room was a cool, comfortable 72 degrees.   It's so ridiculously easy to put together and get going.  The instructions are illustrated and really easy to follow. I'm not handy, and this was REALLY easy to set up. My favorite features are the window venting kit with adaptors (so I can close my window and blinds further than with most units), remote control, and 3-in-1 functions. This unit is so lightweight and rolls for easy moving. I can't imagine living without it now!
