    I needed additional Contact Sensors and this bundle did the trick. Easy to install. My pre-existing connection detected the new additions almost immediately.

    Ring sensors are easy to use and work well in the Ring security system. This system with these sensors is an affordable way to have a wide security system considering how much you are protecting.

    Was really hoping to find one of those Ring Contact Sensor 6-packs (as that has the best value)...but, I believe Ring has moved away from those 1st gen contact sensors. These work just fine. Haven't searched in a while, so I don't know if Ring offers a 6-pack of the 2nd gen sensors. If so, and you need that many, that's the way to go... #math

    The ring sensor for door and window is very easy to install. Took me about 2 mins to install. The setup with thr ring app is very easy as well. Definitely recommend. Only negative point is its size. Though it fits fine.. if it was smaller it wouldnt be so easy to see.

    I've had these for a few months and I must say they were easier to install than the gen 1s and work much flawlessly. Definitely worth the extra couple of bucks. Although bigger they pack more tech
