What Customers Are Saying

Customers overwhelmingly praise this voltage tester for reliability and intuitive light indicators that clearly show voltage levels without complex displays. The built-in flashlight significantly improves visibility in dark panels, while the compact design and probe storage snap-back feature earn consistent approval. Most appreciate the confidence it provides for safely testing outlets and verifying breakers are off. A small number mention probe tips feel too short for stripped wires, the plastic covering occasionally slides off, or the GFI button trips too easily. Despite these minor issues, reviewers consider it an indispensable, well-built tool that outperforms cheaper alternatives.

Two testers, both rubbish

Would Not Recommend

My Lowes was selling this tester in a package with the NCVT-1XT, a stripped-down model with just a single range and no flashlight. The NCVT-1XT stopped working shortly after I first put the batteries in (and, yes, I tried a fresh set). The fancier tester sometimes works, but only on the low voltage range. Sometimes the flashlight works; usually it flashes two or three times and goes out again, as another reviewer mentioned. These are just junk.

Excellent tool for performing electrical work.

Would Recommend

The tool is easy to use, hover the wand near the wire in question and it will beep with an audible cue and show red if a current is present. The flashlight also is handy for illuminating the back of electrical boxes. Thanks to this device, I was able to confidently add several smart light switches on my own and save a few bucks vs bringing in an electrian.

Works as described.

Would Not Recommend

Simple way to ensure the outlet is not energized before starting work. Was able to map out all the circuits in my new home to the breaker panel with minimal effort.

One trick pony.

The probes don’t fit into a duplex plug. But a Sperry, which does.
