What Customers Are Saying

The Klein Tools AC Duplex & GFCI Tester is described as a useful and easy-to-use tool for tracing circuits and testing voltage, as well as identifying issues with outlets and GFCI receptacles. Customers appreciate its simple and intuitive design, with illuminated windows indicating the voltage level without the need to read numbers on a display. However, some users found the probes to be too short, making it difficult to test outlets and wires, especially in tight spaces. Additionally, a few customers reported the GFI test button as being too sensitive and easy to accidentally trigger. Overall, the majority of customers seem satisfied with the tester and recommend it as a valuable tool.
