Scrap out of the box. A screw was missing from one of the wired inputs. I tried removing the screw from the replaced GFCI and couldn't get them to work even though they are the same size. Also comes with (1) screw to fix socket in box instead of (2) as required. This (1) screw was loosened in the box. Quality control nightmare. definitely POS. I can't get this to work.
