Review: Best voltage tester I've used! - This non-contact voltage tester is the most durable and reliable hot stick I've used, including ones from Klein, Fluke, Milwaukee, and other Southwire models. It is very sensitive and accurate, and extremely handy to use in troubleshooting situations. If you are about to work on something though, always use a multimeter to check because hot sticks are not always trustworthy; doesn't matter the brand. That being said the flash light on this thing is bright! The nice thing is the light stays on once you release the button, whereas other sticks you have to keep it held down. It also has a flashlight on the testing end too, so it helps light up inside the box you're poking around in. The water resistant rating is a nice touch too. The only problem I've had with this tester is the rear cap where you put the batteries. If you over tighten it, drop it from high up, or it just wears out, the cap may crack and prevent it from tightening on the threads enough to make contact with the batteries. That is the only thing that has caused me to replace it. The pros definitely outweigh the cons though, as this thing is definitely the most premium option out there. I highly recommend this tester to licensed electricians, or DIYers that like to own nice tools.
Review: MUCH better quality than the other popular NCVT brand - I tried 2 different models of NCVTs from the other popular manufacturer before buying this one. This one is much better quality. With the other manufacturer, I had one NCVT arrive DOA and another arrived with its screw-in battery retainer broken. This one came well-packaged and whole. I like that it has 2 LED lights - one on the front next to the tester end, which is dimmer but adequate, and one on the back, which is bright enough to light up a decent portion of a darkened room or garage or attic. Another thing I like is that the battery compartment end has a rubber O ring to help keep water out. I tested this out on both live and switched-off outlets, and it worked fine on both, including GFCI outlets. I do wish that the 12V button did not have to be held down in order to maintain the lower voltage range, but that's a very minor inconvenience. I'm very happy with this tester.

## Questions & Answers

**Q: Why doesn't this tester work good with a dimmer switch,  4 way switch or some rocker switches when holding it right on outside of switch ?**
A: Possibly have low battery. Dimmers that don’t have a off switch will let electricity pass through. Some testers pick up low voltage amounts. Not enough to shock but enough tester show electricity is there. Buy a tester with sensitive adjustment .

**Q: Will this differentiate between cirucuts with no voltage on the breaker board in a house?**
A: Of course it will. If there is no voltage reading at the input of the breaker, there is no voltage at the breaker. To check if voltage is coming to the box, check the main breaker. If there is no voltage at the supply side of the main house breaker, check the meter supplying voltage to the house. Check each breaker to isolate. Truthfully, I don't understand your question. It's a voltage detector and you are the operator.

**Q: Battery easily changed on this unit? How...screw cap? My old Fluke is impossible to change battery so waste of money.**
A: The rear of the unit, (the bigger torch) has a cap that unscrews fairly easily. This unit also has a self test that means the unit will automatically shut off on startup if the battery level is too low.

**Q: automobile voltage?**
A: For electrical house voltage

### ⭐⭐⭐⭐⭐ A beefier hot sticks
*by A***R on March 12, 2026*

It’s rugged and the flashlight is decent. It’s a little bulkier but it is definitely worth it. I have had over half a dozen of the more popular brand fail on me. South wire hot sticks are the right sensitivity and the beep is the best. Just my opinion. Journeyman Forman electrician
