Review: Very nice! - This is a great little meter! It was easy to install on an old MGA sportster where the original water temp gauge had been damaged. I taped the sensor to the valve cover with some muffler tape. The display range is perfect for an auto. This gave me a functional and nice looking temporary gauge while waiting for a final authentic gauge replacement.
Review: Monitoring - Nice thermometer with a scale and digital read out for monitoring temperature. Bright display, easy to see read-out, good value for the money.

Nice thermometer with a scale and digital read out for monitoring temperature. Bright display, easy to see read-out, good value for the money.

### ⭐⭐⭐⭐ Trolling motor pwm controller
*by A***Y on January 16, 2026*

I put this on my pwm controller for my trolling motor to monitor the temperature of the board. I checked it with other temp probes and it's very accurate. Very nice and crisp display. I have two issues with it, that are small. Not water resistant and the screen is small and I struggle to see the numbers from 4 feet away. Other than that, useful and accurate
