We ordered one of these and had to send back because the central supports seemed to be racked or out of line, making it impossible to align the drum and bottom lens perfectly.  THe edge of the lens or disc was visible just below the bottom of the drum, which is fine except that it wasn't consistent all the way around -- one side hung lower than the other, and no way to adjust it.  Also, one side of drum was slightly dented and would not pop back out.  I suspect the piece got dropped at some point.  Wayfair was gracious to replace it for me.. I will update and downgrade the stars if the replacement also has issues.  

Pros: Nice looking, bright shade, pretty finish.
Cons: Not adjustable if all the parts don't come together just right.
