    These drive the kids nuts but I like knowing when doors and windows are left open. Needed a total of 19 in all and couldn’t be happier. Works well with the indoor cameras and the alarm system

    Works as advertised. We use these on our children's windows, mainly for peace of mind from intrusion. Links effortlessly to my existing Ring alarm system and app. Also has a 'tamper' notification of the kids decide to sneak out!

    So fast and easy to set up, unlike my ADT SmartThings. I love the Ring security system and these are just another easy addition to protect more windows or doors. I even rigged one to be a garage door sensor.

    Re-Did my home security with these all over. Easy to install easy to use and easy to access the battery when they need replacing in 3-4 years. Definitely worth it if you use ring/Alexa for the rest of your home.

    They work with gen1. We bought the alarm system quite awhile back. We needed to add sensors. I don't have the alarm monitored. We need a text alert not an email.
