Though it looked online even when received physically, this is a cheaply made item which is too expensive for what it really is.  My husband took forever to mount it and was very frustrated w the poorly made item.  The screws didn't fit quite right, very finicky.  Finally after 40 min, he got it set up and we wanted to fit an energy efficient lightbulb in there but it couldn't fit- wasn't designed for that.  So we had to use a regular lightbulb.  We have it in the wall now and will use it for the next little and see how it works out.  Even now, its arm swings from side to side awkwardly and stiffly.
