One lamp took 5 minutes to put together.  The other lamp I worked on for over a half hour.  It still would not screw together properly.  For the money I paid it should have been easier.  I finally gave up on the second lamp.   I am a bit frustrated.  In addition I hate that these lamps were not packed in biodegradable packing.  I just called customer support and they were willing to work with me on a replacement for the lamp that did not screw together properly.  Greata customer support.  Thank you.
