    Installed a couple of these with ease. On one sensor that I messed up on the setup order and go stuck, customer service was able to quickly walk through the reset procedure and start over.

    These little guys expand your network of security. Please will connect with your Ring Alarm and you can monitor more doors and windows and what comes in the box with the Ring Alarm only.

    Needed some extra door sensors; quick to set up, extremely long battery life (haven't had to change battery since purchasing) and so simple to set up (required you have the Ring alarm hub)

    This product is great but its its cheaper to buy the multi pack instead of individual pack. You can know if anyone opened the doors or windows.

    Can't go wrong with Ring. For only $100.00 p/ year it is a no brainer. I have had Ring for over a year and we have had absolutely no issues with any of the sensors. Very easy set-up.

    These sensors are simple and easy to install and link up to the entire system. The whole Ring system is well worth the investment and goes above and beyond all the contract big name systems out there.

    I bought these to add extra sensors to my ring alarm system. I like these because they are easy to setup and install. They are also very nice because they let you know if they have been tampered with.

    Just open and followed the easy steps to configure. Note: Work on setting up 1 device at a time and next to the base station. Once the link is established, place where needed in the house.

    These Ring contact sensors work great! They have never lost connectivity in the year+ that I've had the system, and no battery issues either. Highly recommend.

    These door sensors work exclusively with Ring alarm and are an easy add on accessory to expand your existing system. The magnet can be removed from the half that does not contain the battery, and I've done this for a more low profile installation. I have had a sensor go bad from the solder breaking, but ring sent out a replacement.
