I love the simplicity and shape of these fixtures. I purchased 4 to use as accent lighting at the reception area of my office.  They look great with Edison bulbs, and we've received lots of positive feedback from clients. 
The bulb socket seems to be a bit touchy. If you don't get the bulb in just right, the light either flickers or will not turn on. But once we got it adjusted just right, they've been functioning great.
