When I opened the box, I discovered that one of the long base pieces was cracked. This had no impact on the lamp and was just cosmetic.
Additionally, on the end of another long piece, the receptacle part where you screw the bolt into was too far down inside for the bolt to go through the base piece and still make contact with the threads in the receptacle part.  
I had an old bolt lying around that was the same thickness but slightly longer and I was able to use that to complete the assembly. 
As stated in other reviews, it is a little wobbly. 
While I was not happy that there were issues with this particular item, this is my third lamp from this manufacturer, and the other two are beautiful and were perfect.
