    Cheaper than buying the smaller 1 or 2 in a pack and works great with all other ring merchandise.

    You need these guys to expand your system but rest assure there worth it. I’ve owned the system for a few months and every part has been great quality. Easy to program and install. You can really put this system together by yourself with ease.

    These are a perfect add on to your ring system. It added extra protection on additional entry ways in our house. Now all ports of entry are covered. These allow you to detect when the covered door or window is opened.

    Got Ring camera's, well you're gonna need this too. You can get notified which doors have opened/closed and it's fast reacting and no lag. I highly recommend. This is a buy once, cry once for your home security.
