Review: great system - I received this item in a timely manner, and have installed it, and it works. So now it probably won't rain now. We got this so when we are away from the house, and it does rain, we don't have to worry about wasting water. It was easy to install, and hookup to the controller, so we are very happy about the unit. Thank you.

### ⭐⭐⭐⭐⭐ Easy Install, Works Well
*by G***K on June 16, 2021*

This was very straightforward to install. Connect the two wires to the device on one end and the controller on the other, activate the sensor. It reliably measures rain, and my system delays watering on those days.
