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.

## 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

### ⭐⭐⭐⭐⭐ Best tester I've worked with so far and can take a fall W/O breaking like most others.
*by G***U on April 20, 2025*

best live wire tester I have. This small device is a must have when wiring old homes as sometime even if you shut off breakers previous unqualified electricians or DIY's sometime mix 2 breakers in a box that can catch you off guard. I've seen that more than once so now I use this tester to make sure I am safe. even when tracing wires to breakers I make sure I turned breakers back off with this as anything can get you sidetracked nowadays. It's also tougher then all others I've had. Usually drop one of these and they break easy but this tester seems to hold it's own as I have dropped it several times from ladders and it keeps on working. For the size and price of this tester I don't see why anyone would wire without. I had sveral in my electrical tool boxes for years and never used them until I figured out how usefull they really are.
