Was easy to install and cools a 12 x 12 bedroom very quickly. It probably could cool a much larger room as I often leave the bedroom door open to allow it to assist in cooling the rest of the house. The "Dry" mode is a nice feature too! Relatively quiet, we can easily sleep/watch TV when this is running. Kind of hard to see the controls because it is mounted in a higher window, but still okay. Remote works well. Good product so far.
