KAIWEETSVoltage Tester/Non-Contact Voltage Tester with Signal Percentage, Dual Range AC 12V/70V-1000V, Live/Null Wire Tester, Electrical Tester with LCD Display, Buzzer Alarm, Wire Breakpoint Finder

Exactly as expected, practical, easy to use, nicely built, and good looking, besides the good price point. Good sensitivity.

The instructions say it doesn't work with DC, AC only, but it worked on my low-voltage landscaping lighting wires and helped me find the break in the wire fairly easily. Better than digging up the whole wire. Your results may vary.I tested it on AC wires and it works well and you can tell the hot from the neutral by how easily it detects the voltage. If it's hard to detect, that's the neutral.

Good for the price. Worked for my needed job.

Super item, so easy to use and know you are protected

Does what it’s supposed to! Made me feel way safer when doing electrical work. The build quality is fine, but it functions perfectly. Would recommend if you’re feeling anxious about doing electrical work!

I can tell you months after purchasing this. It still is working on the original battery and it is flawless. This device will tell you anywhere. There is a live wire. It works behind walls. It works on existing outlets, and it is a favorite tool of mine when I am working on anything dealing with the electricity in my house. I highly recommend this item.

Works great indoors on standard 120v wiring, but not at all on outdoor low-voltage wires. It did not detect anything with 12v wiring as advertised. Modes are also unclear from description - low sensitivity or low voltage sensitivity? Two different things. Doesn't seem to change operation at all. Battery life not great.
