    Easy to install. A great DIY way to upgrade your alarm system. Use on interior doors as well to track movement. In or out...

    A six-pack was perfect for my needs, leaving only one sensor leftover. One of the sensors got "stuck" in setup mode and became non-responsive. A quick call to Ring got that taken care of, as the representative quickly walked me through a reset process. The sensor has worked flawlessly since.

    I like the Ring system but would like for the contact sensors to be smaller. That will come with time.

    I purchased two packs of these so that I can monitor all the hound level accessible windows of my home. When I purchased the Ring Alarm starter kit I had used the three sensors packed with it to monitor the doors in my home. This is a must have to ensure proper protection of your home!!!

    Batteries did not last as long as I would have hoped. I so not know how long they’d sensors sat on the shelf before I purchased. Worked really well for about 6months then died. One of the two door I placed them on may have only been opened 3 times since it is not a entrance I use often. I figured I would atleast get a year if not more before having to change

    No, I would not recommend this to a friend

    When the weather is good, I like to sleep with the windows up a bit but keep the security system on. These are handy! Stick the magnet part to the window frame and the alarm will go off if someone tries to open it. You can sleep peacefully with cool breezes.

    This security system is wonderful. Doesn’t Require a monthly charge but gives you the option to pay $10/month. I can access everything from my phone and get notifications anytime a motion is detected or window is opened.

    Changed the security system to Ring and was very happy with the sensors. They are a little large compared to the other GE on Interlogix sensors but they have a LED on the sensor which shows when it activates which is cool. I am sure it will affect the battery life so will find out in 3 years

    What’s to say. You stick em up. You pay the fee. They make noise when windows open. What more can you ask for?

    After I got through a few hiccups, these contact alarms work great! Here's a tip... Only activate them one at a time! They each have a pull tab on the back. If you have any issues with them not reading, call ring customer service! They have some of the best customer service :-)

    Bought sensors for my doors to add to the ring system. Ring so far is working for my needs although I don’t use the monitoring they offer as I just want to be woke up if my home is breached and this system accomplishes that. As long as I’m woke up monitoring won’t be needed!
