This unit cools the 500 square foot space I have it in very well. That said, I take issue with it’s ability to cycle on and off automatically. While on Eco mode it routinely will get 4-6 degrees warmer than the set temperature, and stay there for long periods of tome before turning back on. I very frequently find myself manually turning the unit on to cool, then back to Eco mode just to get it running. Overall I am fairly disappointed by the unit and would not buy it again.
