Door Viewer Peephole,Solid Brass 200 Degree Peep Hole with 16 MM Drill Bit for 1-1/2" to 2-3/8" Doors,5/8 Inch Pipe Diameter Door Eye Viewer with Privacy Cover (1, Black)

The peep hole is built well and easy to screw into place with no unforeseen issues, which is nice for once.The hole saw that came with it was surprisingly nice quality!!! It was thick, sturdy, and went through my steel door with fiber core like a hot knife through butter!!I feel like I could drill tons of doors with this hole saw without issue, it is not flimsy or thin in any way.Now the instructions are underwhelming. They simply state something like "drill with bit on both side of the door separately" versus trying to go through the whole door... which is likely not possible with the short length of the bit and saw.I have never installed one so I started with a long drill bit to drill a pilot hole all the way through the door.... this was not a great approach because apparently I was good with up/down tilt but not on left/right tilt.I then drilled the holes on both side of the door with the whole saw and discovered my 2 seperate holes were NOT in alignment to allow the peep hole to be flush from both ends when installed.*****IMPORTANT - I then had to enlarge the hole on the OUTSIDE of the door. The outside exposed portion of the peep hole has a larger surface area so it can cover more hole enlargements and mess ups than the interior side of the door and peephole will allow. So fix from the outside, not from the inside!I was fortunate that I could make the whole big enough yet still able to be covered by the peep hole and no one will ever know unless they pull it off, phew.To do it all over again the fool proof method would be to simply measure from left right of the door and make a mark in the center. Then measure from bottom of the door up to the dot and write down that height value.Go to the outside of the door and figure out how high up to go and then do the left right center again and put another dot. Drill a pilot hole on each dot.Now use the hole saw to drill the holes from each side. At this point, the risk of being off from both sides is eliminated or so minor that fixes won't be an issue

Definitely worth the price, build quality is pretty solid. Drill bit works well, especially for a single use and it's the correct size. Easy to use and install, looks good.

This was super simple to install. Cut right through the metal, foam core door I have. The bit size is spot on for the tube of the peephole. Field of view is excellent. The sharpness isn't exactly crystal clear but it is certainly adequate for its intended purpose. For it's price point and it comes with the bit needed to install I would say 9.5/10. Pro tip. Start on the inside and drill through the door until just the bit comes out the other side. Then start the outside hole. This prevents burring on metal doors and blowout on wooden ones. I recommend a center punch for a metal door to avoid the bit walking on the initial drilling; but it is not absolutely necessary.

A great price for a great product. With the supplied drill bit, it made the job super easy to install.My 4-star rating is because the front lens is plexi and not glass.

Great , and easy to install .

Took me about 10 at most to install. Drill small pilot hole so it barely punctures to the front. Then use provided drill bit to drill halfway through each side. Then screw in peep hole to each side. Beautiful fit.

Specifically bought this one because it had the drill bit included. Drill bit would not cut through both sides of the door as it dulled very quickly. Had to go to the local hardware store and buy another drill bit to finish the project. The peep hole itself is very nice and the cover is a very nice feature.

Very easy to install. Quality looks to be right for what we need. Followed the instructions and it worked well for me.
