Let me start by saying this device is a game-changer for home protection. After my neighbor's house flooded twice, I knew I needed the Moen Flo. Installation wasn't bad - about an hour with basic plumbing skills. The real magic happens when it starts learning your water patterns.

The app gives you real-time data on flow rate, pressure, and usage which is super cool. But here's the catch: historical data is limited unless you pay for Flo Protect ($5/month). Some folks complain about this subscription, but honestly? It's worth it when you consider potential water damage costs.

I tested it by leaving a faucet trickling - within 30 minutes I got a phone call, email AND app alert! The system was ready to shut off my water automatically if I didn't respond. That peace of mind? Priceless.

Now for the not-so-great parts: The fixture identification feature (which took over 3 weeks to activate) is hit-or-miss. It recognizes showers and toilets okay but struggles with appliances like dishwashers. Also, early on it kept shutting off my water during normal showers until it fully learned my routine - annoying but understandable.

The biggest headache? When things go wrong. My first unit had WiFi issues and needed replacement. Later models can get clogged with debris or have sensor failures requiring professional service ($$$). Moen's support via chat is excellent though - they've replaced multiple units for me under warranty.

Bottom line: At $400+ plus installation costs, this isn't cheap. But considering one burst pipe could cost thousands in damage? Worth every penny despite the quirks. Just be prepared for some maintenance headaches down the road.
