Great air conditioner overall like the title says and I own two of these units, but I do have 2 complaints. The wifi set-up can be a pain sometimes and occasionally it doesn't take the settings you command the first time around. The second complaint is that the unit ends up having faulty temperature readings that are much lower than the actual temperature. I've had times where my thermostat and other thermometer read up to 10° warmer than the unit reads and I have to put it on fan mode to circulate air through it for about 20 minutes before the temperature reads properly again.
