The fan is beautiful, but just not easy to operate and set up. The wall unit simply does not work. Only works with app. Some times when we turn it on the whole thing sounds like it is so wobbly that it it going to come off the ceiling. W head it professionally installed by electrician.  When it works the air flow is great. Wish we would have gone a non- wifiapp route instead. There is comfort in simply flipping a switch to work. No switch with this!
