The lights work fine, as far as Being functional. There is a 3 second delay turning on as others have mentioned. 
But my issue is every time I turn on the fan, a chemical/burning smell fills the room. The fan has been properly and professionally installed. There are no issues with the external wiring. The fan did have a slight chemical smell coming out of the box. I assumed maybe from the finish? I thought maybe the running fan was dispersing a painted chemical smell and that it might go away after running the fan a few times. Not the case, the smell is just as strong and only fills the room while the fan is running. You cannot smell it while the fan is turned off or with just the lights on. It is pretty scary. I have not read any other reviews about this issue. 
I do not know what could be causing this.
