We bought two of these lamps and installed them at my in-laws house. They were relatively easy to assemble and install, and all was good, until one of the lamps stopped working. My father in-law attempted to change the light bulb and tripped the circuit breaker. Long story made short - my bad for not noticing when I installed the original light bulb, that the socket was not secured to the housing. To fix the problem I had to add screws to secure the socket (which had been in place in the other unit). So it would appear to just be an assembly line faux-pas, but a fairly serious one. 
So I can't give these five stars, but they are good fixtures, and attractive, so they get four.
