Nuk3y Door Knocker & Viewer: 9/16 in. Bore, 220-Degree View Angle, Satin Nickel Finish (5-1/2" Height) Review

I like this peephole and the knocker is very loud (it even echoes in the hallway of our apartment). The viewer is very wide, and even when placed at the bottom of the door (for short people), it still gives you a full view of the outside of the door. It's easy to install; Remember to measure twice, drill once.

I had a brass observer that I bought on Amazon but recently painted the door and wanted something a little more unusual. The hammer/viewer combination was perfect and fit right in the same hole. It was easier to unscrew the old one and unscrew the new one. I didn't need a screw for further attachment because it seemed to be quite tight. I keep it just in case.

It looks nice and is very easy to install but overall it's pretty cheap. The material is good but the hammer is weak where it goes in. The grooves are too big and the hammer doesn't look like it will fit properly. It was too wide for his seat and almost felt like it had to be bent with pliers or a vise to tighten it. I could work with it, but my peephole was so blurry I couldn't see any of it. Finally sent it back. Maybe I just misunderstood.

Disappointing. The first one I received had a notch on top so I sent it back for an exchange. Eventually, the contractor installed the replacement only to find that there wasn't enough thread on the outside to go through the peephole knocker and into the door. To achieve this, after drilling to widen an existing hole, there was no choice but to add a peephole without a hammer. I ordered another from a competitor hoping they would have a long thread to support the hammer and peephole.
