I was hesitant because it is not your traditional window air conditioner. The measurements were dead on, and it fit in the wall perfectly. The unit comes with a remote control that does absolutely everything so I don't have to reach up or even leave my seat! The controls offer many setting choices which is nice because when it gets too chilly we can lower the fan or increase the temperature. My favorite feature is the ability to set a timer so the air conditioner turns on an hour before I get into my office to cool it off without it running all night. No regrets!
