Had to wait for a replacement canopy but worth the wait.  I installed this by myself with no help.  I also screwed up the ends of railing to ceiling with some heavy rated sheetrock anchors to keep canopy flush as possible to ceiling in addition to screwing to electrical box.  Be prepared to have some time to hang the wires and crustal balls on end.  Metal piece on end of wire is kind of hard to open but i got the hang of it and used the tip of crystal ball to force open the clasp to hang the balls.  I would not want to install another one of these though.
