A little hard to install but it looks nice, it has 2 ceiling caps to stop the air flow back when the fan is off. However, the bottom cover is designed poorly because it is very hard to remove for cleaning purpose. The cover has 2 layers and are connected via 3 tiny plastic sticks, meanwhile the cover is tightly locked with the pan. Sadly, mine cover has broken the first day when I try to remove it to make adjustments. Be careful consumers!
