Documentation is sparse
Hardware works fine but had to search online for code examples. Would be nice to have a wiki link included.

Good value, minor shipping delay
The sensor itself is high quality. One pin was slightly bent upon arrival but easy to fix. Detects water levels accurately.

Robust and sensitive
Tested in a tank setup. No corrosion after a week of continuous testing. Good build quality for the price.

Perfect for my rain alarm
Works exactly as described. Connected it to my STM32 board without any issues. Sensitivity is adjustable via the potentiometer.
