#1 - Makes too much noise. They can send men to the moon, but they can't to make a quiet air conditioner motor!
#2 - It does NOT remove much humidity from the air (it always seems to stay at 70 to 75% humidity. I have 2 humidity gauges and they both read the same.) It makes the air cool but that's only PART of being comfortable in the summer!
#3 - This is a PLUS!  It beats taking a window air conditioner in and out of a window!
#4 - It has no ENERGY SAVER function.  ALL air conditioners SHOULD and it doesn't say it on the box!
#5 - I sure hope I win that $500's cause it will definitely make up for what I paid for it!!!
