Review: A very functional device with some pleasant features. - These types of tools are invaluable around the house. I had one previous and that starting playing up so I went for this Kaiweets model. I think their goods are pretty decent for the price, and sit between the cheap and premium quality in general. After a few months, I can say the tool works quite well and provides a serious DIYer electrician a few more features than your basic NC Pen. Build quality seems pretty robust. The outer plastic is hard and solid and I feel it may take a drop or two but obviously don’t just throw it in a toolbox. Store it in its own box until needed. It’s a safety device after all. The sound and light alerts are absolutely clear and will get your attention, and others around you too. The sensitivity settings as well as the varying frequencies of the sounds and lights help provide more context to the nature of the current. The built-in light is an extremely thoughtful and useful design feature. With one button you can illuminate a dark space under the floorboard as you test for breaks in a wire. I love that it does auto shut off in 5 minutes as I’ve noticed I’ve forgotten to turn it off manually a few times. Batteries are included in the pack which means you can starting using the device immediately. Overall an excellent tool for a reasonable cost, with a very confident 36 month warranty so definitely worth an investment.
Review: Works well - Good quality product that functions well and is considerably cheaper than the market leader.

## Features

- Non Contact: Just place the NCV tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Tests. Handy circuit tester for electricians, and homeowners.
- Safety First: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. At the same time, the screen will be red or green, red means the high voltage and live wire are detected, and green means the low voltage and null wire are detected.
- Dual Range: Only detects AC voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring, etc; The NCV sensor automatically recognizes the voltage and displays it on the bar graph.
- Security Level: IEC-rated CAT III 1000V, Meets CE requirements; The electrical tester is safely double-insulated. High Voltage Alert to warn you of voltage above 70V, the screen turn red, and the electric shock warning symbol is displayed on the screen.
- Compact Size: Bright LED flashlight and backlit for work in dim areas; Auto Power Off after 5 minutes without operation or no signal detection; pen hook allows you to carry it in your shirt pocket. We provide a 36-Month after-sale service, Please feel free to contact us if you have any concerns.

## Questions & Answers

**Q: Will this work through drywall?**
A: I just tried a few walls near light switches where I knew there was elec wires with switches on. The meter would register about "1 line high" near the wires BUT it would also cause the meter to blink the same on places on the wall where there was absolutely no elec wires! I did the test both using the regular setting and also the Supper Sensitive setting. So MAYBE it MIGHT give you some idea where the wires are, but doubtful since there are to many false readings to be sure. That said, this meter works great if you are taking readings without sheetrock blocking it.

**Q: would you recommend this over other models and why?   what do you NOT like about it?  how accurate is it?**
A: I like that it is louder than others, equally easy to use, and the price was good

**Q: I believe a wire that goes from my speaker passenger side rear door is dead, would I be able to use this to test the wire to see if there's power?**
A: You. Will need 12v tester

**Q: Do i manually switch from "lo" to "hi"? pressing the green "sensitivity" button on mine does not switch to "hi".**
A: Mine does not even turn on.

### ⭐⭐⭐⭐ Handy bit of kit
*by M***. on 27 January 2026*

Came with batteries and detected a live wire when 2 others were dead so does the job. Doesn’t have a screen as one of the videos suggested but you clearly know (quickly) whether a wire is live and that’s all I needed it for. I’m sure it’ll be handy
