## Customer Reviews

### ⭐⭐⭐⭐⭐ Match the sensor with the correct control panel.
*by  on Reviewed in the United States November 2, 2022*

This sensor was purchased as an addition to the existing water detection system I have in my home. My experience over several years is being pleased with the system which has paid for itself by the early detection of unwanted water on one occasion to date.

### ⭐⭐⭐⭐ Works well, but,,
*by  on Reviewed in the United States April 1, 2025*

I have purchased before for use in sump pit in lieu of float switch for high water alarm and they work great in mostly clear water but do not do well in sewage water due to all the impurities adding too much resistance.I will keep it though for the next sump job.

### ⭐⭐⭐⭐⭐ Great product
*by  on Reviewed in the United States October 29, 2022*

Works as expected.
