Game changer
Great product. Helped me troubleshoot my ATV much easier than using my multi meter the voltage readout instead of the old style light is a game changer. I also use it checking the batteries on my solar system at my cabin property. Quick and easy.

Heavy-Duty Tester I Rely on for DC Troubleshooting
This has become my go-to tester for DC systems because it’s reliable and easy to use. I use it a lot when troubleshooting trailer lights and tracking down issues like a dead battery on my tractor. The backlit digital display is clear and makes readings quick to understand. I really like the clamp on the negative side—it makes setup faster and more secure. The whole tool feels very heavy duty with a solid, commercial-quality fit and finish. . What you may care about: ··• Accuracy and reliability for DC systems (Meets) ··• Usefulness for troubleshooting electrical issues (Meets) ··• Clamp-style negative connection (Meets) ··• Build quality and durability (Meets)

did not work straight out of the box. Worked on the second try. I will see how it goes.

Very handy and accurate
I just received my order the the quality was better than expected! I tested a couple of 6v batteries from an RV and they tested exactly as my $$multimeter.
