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, Polished Chrome)

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

Great , and easy to install .

Great peep whole sight with bit

Very easy to install. The only complaint I have is that the part you look into is not clear. I think it’s plexiglass. I wish I had gotten a glass one. I can live with this, just wish it was clearer.

Easy kit with clear instructions.

Looks good just wish my contractor put it lower on door as I have to go my tip toes to use. Like the cover.

The drillbit that is included doesn't work for most solid core doors. The pilot drill bit is fine, but the hole saw clogs up and won't let you drill past 3/8"-1/2" into the door. I ended up using a different bit from both sides to align, then taking out the center bit and slowly gnawing my way through the door. Once I had the hole, the unit installed really easy and I used a quarter coin to tighten. It works well if you already have a hole.The small cover that comes with it is a great add on as well, as it prevents people looking in or seeing when you look out. It's a bit stiff at first but loosens after a few days of use.

Works perfect and looks great in my door
