I ordered two lamps - one went together very easily. With the other it was almost impossible to get the stem segments to screw together, and in the end I had to force them so a lot of the screw parts are showing above the two junctions. It works but is not the best and forcing screws is against my nature.
Both of the lamps give great lighting and I am very pleased with that. If the screws had worked it would have been 5 stars.
