Difficult to install - a  real struggle trying to line up the screws to the holes in the plated ring; had to cut away some of the insulation that comes on it and then it took way too long to line it all up.  A very frustrated husband was ready to throw it through a wall!  After about 2-1/2 hours of trying to align it, we had success.  Then, once the entire light was in place, it was wobbly and lopsided.  Needs improvement in the design.  Would not recommend it.
