I recently purchased and after a great deal of difficulty installed a Maxim flush mounted LED ceiling fixture. The mounting system was designed by an ***. The hanger bracket provided did not work with the composite ceiling fixture in my 37 year old house - the screws ran into the bosses. I jury rigged a replacement but then had to blindly try to feed two screws from the bracket thru the fixture. There are so many better ways to do this starting with providing a universal bracket and ending with no blind feed throughs that I would recommend other vendors.
