Really like this unit, blows cool air immediately upon turning on the unit.  Setting up the Smart/Wifi option was pretty straightforward, took a couple attempts to sync.  Like the ability to view the watt usage and start the unit when not at home.  While the unit is quieter than my previous Kenmore AC, I did notice sound associated with drain pan water hitting the fan/condenser.  While the drain plug can be removed to drain the water, apparently it is by design to keep the condenser coils cool.  Overall, very satisfied with the purchase.
