Installed this in my bathroom a few weeks ago. Installation was easy - I'm by no means a DIY superstar but this was an uncomplicated affair. Don't be intimidated by the prospect of working with the wires or electricity. 

A few additional notes:

- Having a partner in crime for this install will make your life easier, especially if you want it level.

- My installation is upside-down; the sconces face down and not up. If you're installing it as shown in the photos, be mindful that you're going to need plenty of room above the fixture to ever change the light bulbs.

- It's extremely difficult, if not impossible, to get all four of the sconces parallel to each other and to the wall. The sconces slide over the socket and are held in place with an inexpensive clip. If you're the kind of person who obsesses about such details, do yourself a favor and look elsewhere. It's not really noticeable to others unless you point it out to them, but it *will* be noticeable to you.
