PRIME-LINEU 10313 Door Viewer, 9/16 In. x 180 Degree, Solid Brass Housing, Glass Lens is U.L. Listed, Classic Bronze Plated Finish (Single Pack)

Very easy to install in terms of the actual product and very clear view outside. Now I did make 1 mistake in drilling the hole. I bought a drill for a wood door and it didn't work out because my front door is metal! I did not know this. So I made a mess of things initially before I realized something was wrong. My fault completely. I love how this door peeper has such a great clear and wide view. From outside in, you cannot see anything as well. I don't know if there are reverse door peeper tools that someone can use, but if there is, they'd only get a view of the stairway...so I'm not worried. To tighten the peephole, I used a quarter and it worked.

It was challenging to find a 1/2" bore size (middle circumference that goes through the door). This was only one of two that offered this size, the Aged Bronze finish I needed, and with good reviews. Come to find out that the 1/2" is actually 9/16" which many others are listed at. Regardless, this was very easy to install, seems to be of good quality, got high ratings at a very reasonable price. The only recommendation is to make it 200 degree or more viewing area rather than 180 which is smaller than most others. I figure 5 degrees on each side will be unnoticeable given it fit all the other parameters I was looking for.

i remember back when i picked my last peep hole and picked the best vlarity onbthe floor. this is notably clearer.i replaced cause i got alcohol on the lense, and thinking it was dust causing smudge used more alcohol on a q-tip and clearly fouled some coating and it gave it a cataract of sorts.new one had a visible imperfection of centering from the outside and only by my over analyzing on the inside very edge only along the edge, and considering that is still far better & wider than a common 3 or so brands at a big local store.its true, 180 is full view requiring glass to be above any rim, so shame on everyone selling 220° views. yeah we at first hear a bigger # and fall for it, which i'm sure is why its common. but i wish we'd go back to a more litteral society.anyhoo, nice! i put a small bead around base edge before tightening as i live in a rather humid climate. Wont see till tomorrow if i marred it any with fingers on it installing and a microfiber cloth. it look like maybe but it could be dust from the cloth sitting a week or two after washing.In other words, I overthink everything and still like it. great analog solution.

It's holding up. Fairly easy to install

New front door gets a new peep hole. Works great.

This door viewer was a perfect replacement for my previous one. The old lens had gotten scratched up by various door decorations throughout the year. This made it very difficult to clearly see who was on our porch. But the problem is solved. This door viewer was very easy to install, it looks great, and the view is wide and clear.

It broke during installation as I was trying to tighten it for proper/flush seating of outer lens.I bought it because I painted my door and I believe the classic brass color would look great. The style and look of it are really nice but broke too easily.

Easy to install clear vision
