Review on MR CARTOOL Automotive Power Circuit Probe Tester 12-24V With 33Ft Extension Cable For Car Truck Motorcycle Vehicle Electrical System Diagnostics by Scott Bradford

This handy tool, MR CARTOOL, is a great addition to any mechanic's or DIYer's toolkit. With its long 33ft extension cable, it allows you to easily reach any part of your car, truck, or motorcycle when diagnosing electrical problems. It's also able to test for 12-24V power circuits, which is perfect for a wide variety of vehicles. However, we found that the probe tester doesn't seem to consistently detect circuit polarity, which can be frustrating and time-consuming when trying to diagnose more complex electrical issues. Additionally, the user manual could benefit from clearer instructions on how to operate the device and interpret the readouts. Overall, while MR CARTOOL isn't perfect, it's still a useful tool to have in your arsenal for basic electrical system diagnostics. 3 out of 5 stars.
