It’ ok for a cheaper little unit. My bedroom is apx 10 x 12 and this cools it down fast. My apt is shaped strangely w rooms separated by long halls and this pushed air down the hall and cooled my bath and my dining area. Even came w a bit of foam insulation(I bought more). Worth the money. Loud, but, they all are at this price point. Lost stars because arrived with large dent in front casing. Quite large dent. My electric bill was also huge. Unusual!
