Ordered three of these for my new house.  I love how they look.  They are simple and contemporary with the capability of lighting up the area like Times Square.  We put LED's in  dimmers on all three.  Our ceiling has 13.5 high ceilings.  The fixtures have a 5 foot maximum drop from the ceiling.  Would have liked them a little longer do to the ceiling height in our kitchen but they still look great.  Perfect over the dining room. I chose to go with the same fixture as the kitchen and dining are open and using the same fixtures really tied the areas together.  I can't speak to installation as I had electrician install.  They voiced no complaints in that area.  Fixtures delivered quickly and as always, working with Wayfair was great.
