Mounting this light fixture was a nightmare!  The directions that came w/ it were not for this fixture.  The screws that came with it were a 1/2" too short.  Lining up the tiny holes with the screws was nearly impossible.  The light fixture itself, although beautiful has some design flaws in the manufacturing and it took some finessing to assemble.  After a trip to Lowes to buy longer screws and a few hours of crying, cursing, and screaming, the two fixtures are quite beautiful.  I purchased these on sale, so for that, I am also pleased.  Mounting these lights is a two person job.  Take my advice and before trying to mount this fixture, pick up a package of Machine Round Combo w/ Nuts Screws #8-32 X 2 inches...it will save you a lot of time.  I have hung many light fixtures in my day and this was by far, the worst installation process I have ever encountered.
