Newhouse HardwareMCHBV Wireless Mechanical Two-Note Chime and Door Button with Built-in Viewer, One Size, White/Brass

I opened the box and saw how the device was well protected and I was confident itnwould work fine. I removed the old (20+ years) ringer cleaned the two ports of accumulated dust and installed the new device. It lined up perfectly; no need to drill new holes; shortened the turn shaft; screwed the devive in place and it works Perfectly!

The media could not be loaded. We have a 1980’s condo that has an metal entry door with a mechanical (non-wired) doorbell mounted on the door right below the glass peephole. So installation was fairly easy but I needed to spend $10 and get a 1-in Bi-Metal Arbored Hole Saw which I picked up from Lowes after much research. Do yourself a favor and get this as it took 30 seconds to cut the hole. I did not use the template. We already had an older doorbell just like this which was original to the condo circa 1985. Problem was the original hole for the old one was about half the size - so it needed to be drilled out larger- as well as a bit lower so the housing for the button mechanism on the outside of the door didn’t hit the bottom of the peephole. As others have mentioned, the biggest pain (and my reason for 4 not 5 stars) is the metal piece which is attached to the button. It’s scored but nearly impossible to cut down to size unless you have a hacksaw and a vice. Nippers didn’t do a thing to cut it. The tip of it has a hole predrilled in it that makes snipping off the first section easy but after that there are no holes so I took a pair of pliers and held the thing steady while someone else twisted it inwards and bent it enough so that the outer plastic cover could be put on. So it’s now bent but hidden inside and the button works perfectly. Done. Another option would have been to drill a couple of holes in it so you could weaken the metal and snap it off. The bell is plenty loud. I just need to touch up paint one side in a small area where the plastic cover didn’t sit in exactly the same place as the old one. I’ll upload a video of the bell sound with this review. I also used a label maker to add Last Name and house number. Looks much better than hand writing it in as suggested in the instructions.

We moved into a condo that was built in the 70s and with all the reno that needed done, we couldn't afford a new door. After we painted the original door, the old unit went out of commission and we needed something to cover where it was. This worked perfectly. And we decided to follow the instructions and "print name on the other side of this card" and leave the card the way it came in the box. 😉

Somewhat difficult to install if you don't have the proper tools! Otherwise works great. Bought this ad a replacement Ford a similar broken product and it works better than the original! Old school but works.

Just work a few days, after that when press the knock , it can’t go back to normal. Won’t buy it again.

This is a good replacement for an older version except you will have to enlarge the original holes. It then installs with ease.

This chime has a nice tone but, as others have noted, it is quite soft. It will work if your house is small and quiet. The moving parts are mostly plastic and may stick if you do not release the button quickly. You have to drill a 1 inch hole in the door which could be a problem with a metal door. You would probably have to mount the outside button on a block of wood with the 1" hole to accommodate the part which hangs out the back and then a 3/8" hole through the door should suffice for the operating shaft.

used for mthe correct size.ephole. works great. Wish the metal piece inside was a bit easier to break to make the correct size.
