Reliable detection
I used this for a rain alert system. It triggers consistently when water bridges the gaps. Very satisfied with the build quality.

Does the job
Simple and effective. Wish the cables were a bit longer, but I extended them myself. Detection is instant.

Good value but sensitive to corrosion
Functionality is great for the price. Just note that leaving it submerged constantly may cause corrosion on the traces over months.
