## Customer Reviews

### ⭐⭐⭐⭐⭐ Keeping pond beautiful
*by A***  on April 29, 2025*

Keeps pond level perfect, used with relay to turn on pump.

### ⭐⭐⭐⭐⭐ Seems Solid
*by H***R on September 6, 2023*

Using this to monitor water level in a swimming pool in conjunction with an ESP8266. Selected this one (model ZS12010-2) as it is stainless, claims plated contacts on the internal reed switches and is about the right size for my application. The black pair of wires correspond to the lower float. The red pair for upper float. Working well with 20 ft of wire from float to microcontroller. Too early to tell how it will hold up over time. A more detailed description can be found at the outpost4 dot org blog.

### ⭐⭐⭐⭐⭐ It will  work.
*by R***N on May 11, 2024*

The item is fine. It will be used on a trout pond.
