They were easy to put on and look great. I was afraid they would stick out too much but they look perfect. The first one we put on we just used a regular wrench and it scraped the paint off the screw (in the last picture). Once we attached the one included in the box which cut off the scratches. Easy enough to do it yourself. It may take a little effort to remove and tighten the nuts, but overall this is a pretty easy project! I like the way they look.
