This light was extremely difficult to hang. It's almost impossible to line up the screws in the ceiling with the holes on top of the light.  However, I ended up tying string to the ceiling screws and guiding the light into the screws.  It took about an hour and a half, and it should have taken 5 minutes, but it got done.  The light itself is very pretty.  When it's on, the walls have the same pattern as the outside of the light.
