Fan looks nice.   Installation was pretty easy, I'd suggest doing a dry run on the floor before hanging it up.  Relatively quiet, and it moves air well too.  Light is nice,  I like the 3 settings for brightness/colour.  So why the low rating?  The control module is glitchy.  When you run the fan at night,  you need to turn it on (lights and all) using your main wall light switch.  To turn on the fan, and to turn off the light (for sleeping), you use the remote.  All good.   Until at 3 am when you turn off the fan using the remote rather than get out of bed.   This leaves the wall switch in the ON position with no light, no fan.  If you leave the switch in this position for too long with no light or fan, the unit STOPS working.  Can't turn the light or fan on anymore.  You need to turn the wall switch OFF, and leave it off for 15-20 minutes before the unit resets itself and resumes normal operation.  That is very frustrating.
