I have two, they are just the right size to put in my kitchen window to keep my kitchen and dinning room cool and one in the bedroom to keep my bedroom and living room cool just in case my A/C stops working or the power goes out and I can plug them into the generator. I put them in the windows in late Spring and then remove them in October.  In Texas, you HAVE to have a backup plan to survive the HEAT!!!  It blows out a LOT of air and the air is very COOL! Since the pic was taken, I have fixed the power cord so it doesn't lay across the sink. Would hight recommend.
