As previous reviews have stated, the instructions are lacking and the light must be altered to be installed. My husband took the "spacers" off to more easily mount the light. (He says DO NOT USE GREEN SPACERS.) The poor instructions caused a more lengthy installation time.
Attaching the crystals was quick and easy for me, it didn't take more than 10-15 minutes, overall.. I attached all hanging pieces after the light was mounted. There were two additional crystals - either ditch or add to the middle. 
HANGS BEAUTIFULLY! The four-lights in this mount help all the crystals to glisten. White fabric shade is great- make sure you have clean hands.
Overall, worth it! I'd purchase another and now that we'd figure out how to install it then pain would be greatly reduced..

Pros: Beautiful!
Cons: Lengthy installation.
