Newhouse Hardware 2-Note Mechanical Door Bell Chime and Door Button with Viewer, Silver

This worked great after some engineering time to think it through.The existing door holes did not quite match with any of the various units that I purchased, but after some physical reviews, this model could be easily modified.I wanted to keep the existing decorative plate on the outside of the door because it was a special design to the condo throughout the complex.I rotated the unit upside down. The directions then required an easy swap of the sliding door spring locations.I also swapped locations of the existing push button and eyeglass, and replaced with the new that are supplied with the unit.

Instructions are difficult read. A little patience and you could figure it out.

For whatever reason -- once I click the cover to the back plate that is on the door, the mechanism that hits the chime (or it could be the chime itself) is somehow hitting the cover plate which in turn is muting the chime -- so there's no sound. Or, it sounds awful since something is obstructing it. When you take off the cover, it works perfectly, sounds great....They should've allowed for more room or clearance on chimes.

Life saver. I couldn't find this doorbell anywhere. Leave it to Amazon to have just what I needed.

I bought this doorbell because my old one fell apart literally. When you pressed the button it did nothing. I was able to buy this as a replacement and pop it right in as it’s universal if you already have a similar set up. It took me about 10 minutes to swap out. I’m handy so maybe 20 minutes for a non handy person. Who knows, maybe I will get a ring doorbell at some point. For right now this works!
