Review: Don't Run Over With Lawnmower - Works GREAT until you run over it with the lawnmower. Then it doesn't work so well. Did this twice with two different sensors. Needs a feature that connects better with my brain to not run over it, twice.
Review: Easy to add to my system. Seems to work well. Useful! - This sensor was easy to add to my system. The test the instructions recommended showed the calibration was correct out of the box. I have no way to confirm its accuracy in the ground, but the readings seem reasonable. In any case, I believe it will help me determine how often I should water my avocados!

Works GREAT until you run over it with the lawnmower. Then it doesn't work so well. Did this twice with two different sensors. Needs a feature that connects better with my brain to not run over it, twice.

### ⭐⭐⭐⭐⭐ Easy to add to my system. Seems to work well. Useful!

This sensor was easy to add to my system. The test the instructions recommended showed the calibration was correct out of the box. I have no way to confirm its accuracy in the ground, but the readings seem reasonable. In any case, I believe it will help me determine how often I should water my avocados!

### ⭐⭐⭐⭐ Works Great
*by M***N on August 19, 2025*

My unit works great, right out of the box. The base unit recognized the new sensor immediately and the calibration appears to be accurate, right out of the box. (I compared the reading to an old soil moisture meter I had lying around the house)
