The compact, pocket-sized design with audio alerts enables quick checks on outlets, switches, and wiring. Customers describe it as an essential, affordable tool with included batteries and auto-shutoff.

Did not work

Would Not Recommend

I'd give 0 stars if that was an option. It simply did not work. Totally failed to identify a live wire.

Good for novice users

Would Not Recommend

Decided not to buy because no one knew how it worked. Instead I purchased a digital volt meter with a numerical result. This is a yes/no logic and not good for measuring battery voltage or voltage drop issues.
