Peace of mind for a few dollars? Deal!
After having had a water heater leak that cost over $10,000 in repairs, I saw an advertisement for FLO and bought one. It's been installed for a couple of months, and not only do I know that I am protected from another flood, but I have learned important information about how I use and may conserve water. It's a highly recommended IoT device. Being able to monitor and shut off water to my entire home is much better than worrying when I am away from home.
