What Customers Are Saying

Customers overwhelmingly praise this electrical tester for its accuracy, reliability, and ease of use. The large digital display, simple plug-in design, and intuitive red-green indicator lights make diagnostics fast and accessible even for those without electrical training. Many highlight the integrated flashlight as unexpectedly practical for dimly lit spaces. Reviewers consistently describe it as a must-have tool for both professionals and DIYers, offering exceptional value and professional-grade performance. A few report intermittent issues or occasional false positives, but these rare concerns do not diminish the strong overall satisfaction.

Worked great initially

Would Not Recommend

The battery cap (screw on) has failed after about 8 months. I started having trouble with the light and NCVT test coming on after about 6 months, cleaned the contacts and it was fine fine for a bit longer, but gave up after a few weeks. I cleaned it again and no joy, the thing is dead. I would not recommend this dual purpose tester. The contact from the screw on battery cap to the body of the tester is meh at best.
