One of the saddles was crooked at the top where the shade would rest on.  This would lead to a crooked shade.  Also, the part where the light bulb apparatus goes into the base doesn't "snap" into place so it just sits there loose.  So when touched the shade would wobble.  It seems poorly designed.
Looks nice and the glass seems durable.

Pros: Looks nice and glass seems durable
Cons: Poor design for light bulb and shade.
