I purchased 6 of these sconces in total. They are very pretty, have soft light andlook great in our treatment rooms when we don't want to use the harsh, florescent, over head lighting. 
I had an issue with 2 of the sconces where we could not separate the ceramic nut to put the light bulb in place. They were put on so tightly the whole fixture was rotating. I contacted Wayfair and they sent out new ones to replace them. I've always found their customer service dept. to be friendly, fair and accomodating!
