Does what it’s suppose to do. Did a quick test licked my finger put it over the contacts. Within seconds I received the notification on my phone - “The Kitchen sink Flood sensor alarmed” Then received a automated phone call, that the sensor tripped. I bought two for now one under the kitchen sink, the other right under the water pipes for the washing machine. I will eventually pick up some more. i.e. - bathroom sinks, toilet, etc...

Easy install and works great with my Ring Alarm! Tested them and they work great. Glad to have the peace of mind knowing I will bet warned when water is detected. Since I live in a warm part of AZ, I doubt the Freeze sensor part will come in handy; however, you never know when weather patterns may change and I'll get the opportunity to get a freeze warning as it has lightly snowed here once or twice and it is better to be safe than sorry!

I tested these out in a bowl of water before placing them in service. They work, and it's a quick notification to your phone/Ring app saying they detected water. They are super small too (maybe 2-3in in diameter) so they are convenient to tuck away and out of sight.

Very simple setup but a must device to have a home. I put it under my ac because I had leaking issues and I received instantaneous alerts.

Easy to set up. Small and stylish. Definitely a great product for notifying you when a flood occurs in home.
