I will update this once I actually mount the fan/light and see how it works.....At this point though, I
really like it. This is for a master Bathroom that has no windows or access to be able to install a fan, 
so we went with the next best thing.
It is very lightweight and looks super easy to hardwire install. The side that is black with the cutouts feels like a thick fabricy vinyl? But will do the job, I believe. I'll keep you posted!!
