These are beautiful and they look lovely installed in the new home. We purchased for a new house build and once they were finally installed, it  was past the return window (and I did contact Wayfair but was told there was nothing they could do) for a humming in the fixture.  Our electrician was unable to get it to stop humming and recommended replacing it to avoid a fire hazard. I really felt that even though the return window had closed, with a safety issue, it should still have been replaced.
