Works excellently. This is our third in-room AC and the prior two were a different brand that only lasted 3 years each. This one is clearly a better quality. It cools our large, vaulted-ceiling bedroom easily. It is sleek looking, quiet, and the Wifi integration works well with our very Alexa-enabled home. You have more options in the application than I expected, I was pleasantly surprised. I highly recommend it . ONLY downside - the larger BTU capacity and quality make this unit a little larger than past units but that's too be expected.
