5.0Easy to install and add to existing Ring alarm
These are just like the one's included with the Ring alarm system when you get it. They install the same way within the Ring app. They can be mounted with the included screws or with the included sticky tape. I will that one sensor fell off my back door when I moved it to re position it during install. The tape is meant to be pressed on and not moved. If you do need to re position it then just use a new piece of tape. I ended up getting a different and stronger double sided tape to use and just cut it to shape. No issues with it falling off now. None of my other sensors have had issue with the included tape though, so don't be afraid to use it. As a note, you must have the Ring alarm to use these sensors. They will not work with the Ring alarm base station.

When paired with the new Ring alarm system these work great, and they aren't hard to pair or install.

So far so good
So far so good, I wish they would add some programming features so you could use full functionality of alerts etc even when it’s not armed.
