What Customers Are Saying

Customers overwhelmingly praise this outlet tester for its simplicity, reliability, and effectiveness in safely testing electrical outlets and GFCI circuits.

Voltage tester won't turn on

Would Not Recommend

The voltage tester battery cap doesn't make contact properly, so the voltage tester doesn't work. I tried two and neither worked. If I short the contacts with a wire, it works. Poorly designed piece of crap!
