Bought this a month or 2 back for my new house in college thinking it would do some good in my room. Little did I know it was going to cool 1/2 the house! Pairs with WiFi and your phone, you can set temp and fan speed from anywhere as long as the unit is connected to internet. So convenient on hot days when I’m out, get to come home to a perfect room/house. HIGHLY RECOMMEND buying this over surround AC, saves money, power, and works just as well.
