Although most window/door layouts allow easy installation of these sensors, sometimes you have to be a little creative in making them work. For my windows, I had to make a small metal bracket so that the sensor would clear the screen. It works and is a reliable part of the Ring Alarm System. Buying in bulk makes them a good value.

This model is much smaller than 1st Gen model and is great for tight spaces. It also uses button batteries which are easier to get and cheaper than the lithium batteries used in 1st Gen. Set up is a breeze.

Was a great price for brand new authentic Ring sensors. Was so easy to sync to my system. AA++

We have many Ring sensors - these were the first 2nd Gen type. They we purchased used (open box). Someone had tried to install them and as a result had taken off the coverings for the sticky sides, which were unusable. Fortunately I was able to use them in a place where screws worked well. The sesnors worked fine after I replaced one of the batteries.

They work great! Installed sensors and linked to the ring alarm. Now before I go to bed, instead of having to go around the house to check that all the doors are closed and locked, I can just look at the Ring app. Occasionally I drive away and then think I forgot to close the door (only actually happened once), with this I can check in the app that the door is closed.
