    I had to purchase additional sensors for my ring alarm system. I didn’t have enough with my initial purchase. These are easy to put up and respond well to the alarm. Ring is the easiest alarm system to I stall yourself. I highly recommend this system.

    Easy to setup and add to existing Ring security. I already had Ring security so just wanted to add for rest of the doors and windows. Does not take more than 10 mins to add 2 devices to existing security.

    Love these things. I wish there was a way to where you could move them different places. They are sort of a stick on permanent deal. But they work flawlessly and I have over 12 of them on my windows and doors.

    I needed a couple of these to replace a couple of 1st gen sensors that did not work very well on my doors due to the shape of the trim. They can be separated a bit farther apart than the first gen sensors and work great

    Ring has made it a simple process to add items to your existing security system. You simply scan the code on the contact, then stick each side within. 5 inch of each other. Ring hub picks it up, you name it and it becomes part of the main system.

    These sensors are great. They are incredibly easy to add to your existing system. The set-up process through the Ring app is easy and intuitive; takes about a minute per sensor. Easy install with command strip adhesives.

    These contact sensors work great and are easy to install. The 4 sensors that came in the bundle weren't enough for all of our doors and windows, but this 6-pack was the perfect add-on.
