I've had the AC unit for about a week now and haven't had any issues. The unit does a great job of keeping the room cool and doesn't run more than needed. I like that there are several different modes as well as a sleep timer. The remote and app are also very handy. Another nice feature is that the display light goes out after a few seconds. It's not super bright but in a dark room it is noticable so it's nice that it doesn't stay on.
