Do not buy
Really bad quality. The lens comes disassembled with imperfections. Had to search a bit for the correct way to put it together. I do not recommend it. To save everyone’s time here is a photo I found that will help with assembly.

Works great but please read the review for helpful info.
If you a DIY'er, please note on installing. For best results use a 9/16 wood paddle bit and carefully mark your hole before drilling. Interior doors are 32" and exterior are 36" but always measure them as I have found 32" exterior doors (not supposed to happen) Try to mark height for the smallest adult in the family. You should install on any exterior door which does not have a window or adjacent window next to the door. Security and safety is the goal. Center for exterior door is 18" (36" wide) Measure twice before you drill.
