Unbelievably bad installation instructions, and even worse installation process.  It's a constant game of Chicken or the Egg; you can't hook the wires up until you run them through the mounting assembly, you can't mount it to the ceiling until the wires are hooked up, you can't get to the mounting screws because the ceiling cover HAS to be on when you attach to the ceiling or you can't get it on after.  You end up having to wire the light, have one person hold it, fit a tiny screwdriver into the mounting screws under the collar, get it attached to the ceiling, then try to tuck wires under the collar.  Worst install I've ever had.

After that, you get to hang each of the glass crystals, one by one, with tiny metal clips.

After all of that, we're reasonably happy with the light and the way it looks, but WOW what a process.
