I am shocked that these received such a high rating! I would have returned them if I didn't destroy the insulation trying to get the first one up. There are several things wrong with these light fixtures. 1. The screws it comes with are way too short to get through all of the insulation (and it's a lot) to even reach through the holes. 2. It mounts in the reverse way than most fixtures, since the screws are "exposed", they do have a ball they screw into but it made for a less than quick replacement of our old fixtures. 3. THE GLASS DOSEN'T FIT TIGHT! Once you get it on, you can just spin it around and around, it doesn't fit securely into the fixture, which lets little bugs/dust in. Though they look fine once put up; ultimately, I cannot recommend these.
