    Always nice to have sensors for wherever you need them in your house to protect burglars from coming in that way.

    Purchased this product and one of the sensors came damaged and now in the process of returning it. Purchased other sensors as well with no issues but a bit frustrated that newly packaged product was defective.

    Good security system by Ring

    It works well - one thing I underestimated was the # of range extenders needed. I ended up get a couple of more range extenders than expected. Once I got those in place, the whole system works really well.

    The Ring alarm contact sensor was fairly easy to install. The sensors have to be lined "just right" or they will not work. But other then that I have them for about 4 months with no issues.
