    Love the potential benefit of having this device. Unfortunately, One did not work right out of the box. It has been replaced.

    These sensors are super easy to install. I would definitely recommend cleaning the surfaces before applying them, to remove any grit that can get stuck in the adhesive.

    These are simple to install, effective, and get the job done. My only complaint is that it can get VERY expensive if you truly want to have these on every exterior facing door and window in the household. Ring has a great mobile app to support its security products and inexpensive monitoring plans though.

    These are a little smaller than the previous generation. Easy install using the QR codes and double sided adhesive OR more permanent attachment with screws.
