So, it's important that you know that the light will move.  The line to the light is flexible.  The second thing is the paint scratches easily (which I have asked for touch up paint).  The third thing is that they cast a really nice pattern on the wall when light and look very nice.  They were easy to install and, for me, they suit my modern industrial look that I was looking for.  They were well priced against other options as well.  Aside from the above points (which didn't bother me), I am happy with my purchase
