Bests & Worsts Reviews from Amazon

Edited to add: Using Internet sources for calculating cooling needs, it seems the problem with this unit is inadequate airflow. A 600 square foot room needs airflow of at least 540 CFM. This unit only flows 80 CFM (4.5" X 5.5" cold air output; 5.4" exhaust). Although the BTU rating of 14,000 would be adequate up to 700 sq ft, the minuscule air flow only supports rooms less than 100 sq ft (10 ft by 10 ft). Compare this unit's 80 CFM airflow to window air conditioners with the same BTU rating -- for example, a 14K BTU window AC from GE puts out 470 CFM. Installed in my well-insulated 600 square foot garage with insulated ducting to exhaust the warm air. The drain didn't work properly, so I had to prop up the front end with a 2x4. It ran continuously for 48 hours without getting the air temp below 85 degrees on either Cool or Auto setting. It did remove moisture from the air. After propping up the front, it pushed out 12 to 15 gallons of water in 48 hours. The air temperature at the swinging outlet registers 68 degrees on my laser thermometer after the unit ran a few hours. That isn't nearly cold enough for 600 sq ft. Maybe 100? The merchant wants me to pay return shipping, which is incredible for a defective unit. I don't recommend buying this unit or any portable AC unless you have a very small room to cool.
