I am a single senior woman and it was super easy setup. Love the app and peace of mind I can have immediate reassurance it is working and I am safe. Love that it can also set on nightstand so I can take it on vacation to an airbnb that does not have a CO2 detector. I'm going to get one of their fire detectors too!Show lessUse it well
