    Not much to say here. They are contact sensors for the Ring alarm system. I needed more for my home.

    It works fine. I installed it on a system that had a few sensors and the contact sensors worked but the motion sensors as a hit or miss

    These stay on the windows and doors great. I was kind of nervous about that but no issues with that. Discreet and not bulky as well.

    I had to use my own double sided tape to keep the door and window sensors in place. The sticky stuff provided didn't last 2 hours. Now I am confident that they will continue to work as advertised.

    My Ring alarm system came with one contact but needed two more to monitor backdoor and door leading to pool. This addition was perfect.

    These worked well on our doors but the type of windows we had did not work with the sensors. Check your doors and windows first.

    I am new to the Do it Your self alarm systems. The setup was very easy but the sensors are to big in my opinion. Ring make them smaller!
