### ⭐⭐⭐⭐⭐ Works great, easy connect to base unit. Wish I had gotten it two months ago!
*by A***R on 8 March 2025*

We got this Eufy Security Water and Freeze Sensor with Remote Alerts, to add to our Eufy system base unit. Easy to follow directions to set up. Leak detection should be excellent as it detected even a little water on the test runs. The only problem we had connecting was due to the network password being changed (our error). I'm super glad we got this and it gives me peace of mind that we can deal with any future leaks where this Eufy sensor is placed. And yes, we got it AFTER we had a leak, fixed the faucet, and cleaned up the mess.
