Very cheaply made, hard to assemble and the teeny tiny screw are ridiculous.
If you want to adjust the lamp spacing you have to take out those teeny tiny screws, move them and then put them back.  I thought they would swivel on their own but they don't.  Very disappointed since I paid full price and the next day it was on sale but they wouldn't give me the sale price.   The lamp shades are so cheaply made.   China.
