### ⭐⭐⭐⭐⭐ Works as intended and value for money
*by N***L on November 11, 2025*

Product works as expected . I have to used it to control solenoid using float value for aquarium. Connect the 12v DC power directly to +/- terminals of relay.. Connect one float wire to signal interface and other wire to positive terminal. Now you can use this relay to make it NC/NO based on your requirement
