Beautiful chandelier!  It looks so sophisticated and elegant! 
It took my husband over 7 hours to install, but was well worth it. It comes in pieces with every part needed to be assembled and the directions are terrible. Most of the set up was my husband looking at the product picture to see where things go. 
Two items came broken; one glass arm and one glass cup that is under each candle.  I put in a request to have those items replaced, so hopefully that happens.   Our table is 40” wide and ceilings are 10 feet tall. The dining room is in an open concept floor plan so I can’t give actual room dimensions. I love how dominating and regal this fixture is. We also purchased a linen fabric to cover the electrical chain which I think will make it look even more polished.
The chandelier is on a dimmer switch which is a must. The led light bulbs we also got from Wayfair are so bright it looks like we are in a tanning booth when fully engaged.
