I received these and put them together myself, the instructions were extremely easy to read, one of the washers did not fit so I had to get one of my own, but that was an easy fix. The only thing that I would say, is you may need some extra lubricant when putting the base on. I have a couple that slid on great and are rocking and swiveling and I have, one that is not swiveling so we needed to muscle it a bit to pull it apart and put some more grease.
All in all, it looks like the picture, and we are very happy with them !
