This works well if you know it will fit in your light box. It seemed to fit mine but found mine had a bracket inside to mount an existing jig. I didn't like the design where one screw goes through the socket and all the adapters go into the mounting box. It would be better if you screwed on the adapter plate and then screwed on the plate and base separately. I received it with some major changes. It works. It probably doesn't fit the code.
