Bought this as our master bedroom always cooks in the mid-afternoon sun as we have many west facing windows and we're partially over a non-insulated garage. This AC unit cools down our roughly 330 sq. ft. bedroom quickly so we can now sleep comfortably at night. Only gripe is the fan speeds are a bit louder than expected. However my wife and I don't mind the white noise to keep us cool at night. The wi-fi feature is nice as I can fire it up from my cell phone app anytime I'd like. Glad we purchase, install was pretty easy.
