    Better pricing than purchasing individual contacts. These work great for windows and doors, could even use them for cabinets, drawers, etc that you want to monitor for opening.

    The motion detector was easy to install but I couldn’t figure out how to turn off the sound when I entered a room. After a Google search I was able to find it.

    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.
