We purchased this window-air conditioning unit to supplement our central air conditioning that can't really compete with our sun-soaked main bedroom. It has been great! I cools off the room quickly at night and enables us to get a nice long sleep without being waken up by our baking room. It can be controlled by either a phone app or the remote control - which has been handy. The installation process was quick (probably less than 30 minutes) with two people and the air conditioner had really easy to understand instructions and included everything you need to install (except a drill, if you're going to drill holes to secure the air conditioner).
