Title: Easy to intall
Review: We purchased a house from a builder, and the front door did not have a peephole. We live in the city, so we definitely wanted one, but the builder said it was either the standard door, or a different door with a peephole for $45 more. I found this peephole on Amazon, and am very glad we decided to just do it ourselves. Our door is about 2" think, and this easily expands to fit doors of varying widths. A 1/2" drill bit is all you need to install this - literally takes maybe 5 minutes to install. The view through the peephole is perfect - you are able to see straight ahead, and pretty far in the peripheral in each direction.
