The first chandelier we bought did not work (after we already installed it).  We were disappointed because we liked appearance of this in our breakfast nook.  We called Wayfair and they shipped us another chandelier at no cost.  There was no hassle involved.  We were required to hold on to the broken chandelier for 3 weeks to see if the manufacturer would like if back.  This did not happen, so we were instructed to trash it.  We were very impressed with this.
