I used these over the beds in the spare bedrooms in our FL home.  They are resin.  Very easy to install when you use the proper wall anchors.  I was quite irritated when the first anchor and screw went right through and down the back of the wall!  I had to buy 8 anchors because the ones they provided didn't have a lip on them and they wouldn't hold in the drywall.  When you tried to put the screw in it, they pushed right through the drywall.  Easy enough fix.  Honestly for the price I paid, they could have at least provided good quality anchors.
