Had to replace my old one. Great replacement and easy install.

Easy replacement of window/door alarm switches.
Replacing failed switches without crawling around the basement or opening walls. Great idea. If you can pull out failed magnetic reed switch, then connect same wires to this switch and tap into place. I was able to pry out most failed switches, only had to drill one. Hopefully the installer left a few inches of slack wire.

Too small
They did not work for me.

Replaced ADT Door Sensor Perfectly
It was a direct swap of the old failed sensor for this one. I didn't even need to replace the magnet side on the door itself as it just worked. I'm very happy with the result.

Better price than ADT
ADT was trying to charge me $86 for two similar door sensors. I decided to go Amazon and came across these. They have a a bit larger diameter than my original sensors but are easy to install, fit well and look good. Only rated these 3 stars cause 1 of the 3 was dead on arrival but at this price point it’s not a concern.
