Review: Easy installation. Good quality.
Review: Its a nicely built product. Has held up great for months. Its rather smal and has a clean look and fit. Switch toggles very easily. My only complaint is the locking ring its so thin it makes it not tighten into place very securely. I would up adding a bead of silicone to the back to make sure it stays in place.
