The unit is really strong and covers most of the main section of our apartment. Surprisingly it made less noise than I expected being 10k BTU though we still need to adjust the TV volume a bit when it is running. Wifi connect is super useful and the app crazy easy. My only friction with the app/device is that it resets to eco & auto fan to say it saves energy. This is a pain point because we'll turn it off and on again to manage the power usage and temperature for our newborn during the day.
