Shade and glass diffuser are nice looking. 
Design wise the only thing I don’t like is seeing the metal bars through the diffuser, but I realize this is because I got a glass diffuser instead of a plastic one, so it needs the stability. 
The only other drawback is that the installation of the diffuser is tricky for one person because of the way the washer-diffuser-washer-nut assembly. It’s a few too many parts for two hands above your head! Otherwise the installation and directions were good.
