I searched a long time for the perfect fixture and this fixture is beautiful but unfortunately the quality made it impossible to even use. 
The center metal post, that holds the glass plate in place at the bottom of the fixture, does not line up with the hole in the glass.  it seems the fixture was not a perfect square, with gaps in the metal frame. My husband, who has hung many fixtures, was able to get the glass on, even though it was not aligned correctly, but apparently, overnight,  a stress crack formed in the glass.  After walking under the fixture the next day, the glass came crashing down in 3 large shards. Very dangerous!  We ordered a replacement fixture and upon inspection, the metal post in the middle again didn't line up with the hole in the glass.  Wayfair was great about sending a refund but I'm really very disappointed with the quality. I checked and  having a replacement piece of glass made was well over $100.00. Too bad.  I loved the look.
