I bought this over a month ago expecting a heat wave that didn't come. So I didn't have a need to use it until after the 30 day return period. But now that we've had temperatures in the 90s this week, I've quickly learned that this unit does not "air condition a room". Instead it blows cool air about two feet in front of if. Also, if it's used in a bedroom in Minnesota - a state where we need more sensitive circuit breakers in bedrooms by law - it will trip the breaker after about 10 minutes of use. This was a waste of money and huge disappointment for me. I would not recommend.
