Everything arrived quickly and they are very pretty.  I havent added the cord cover yet because Ill have to move my bed. The question and answer indicated these move from side to side. Now, while there is a joint there, I could not get these to move side to side at all. I quit trying because I was afraid Id break them. There were no instructions, the photo of the page I included, that is it. It isnt hard to figure out the plug in version but if you plan on using the hardwire stuff included in the package, good luck. I dont regret my purchase, they are just what I needed. I took away a star for bad instructions and lack expected articulation.
