1. The instructions are completely worthless! Its just a picture labeled with letters that shows you how it all goes together. No actual step by step instructions.  
2. The chain links that connect the actual fixture to the ceiling plate might at well be soldered together. They are so hard to get apart! I had to use pliers and vice grips to pull them open which of course scratched the heck out of them. 
3. Plan on having a strong helper, you have to hold the entire fixture up while wiring it into the ceiling. 
4. The ceiling plate is JUST narrow of covering the standard electrical box, so there is a small gap on either side that isnt completely covered. 

The end result is great, but there could be some SERIOUS improvements. Long story short - make sure you have at least a little experience installing lights before tackling this one. The lack of instructions is comical.
