Picked this up to help diagnose two outlets that weren't working. Told me I had an issue with a negative wire, pulled the outlet out and sure enough, the wire had popped off. The tool was 100% spot on in diagnosing the issue. Its compact, cheap, and works. Can't get better than that.

Handy and reliable tool — quickly checks outlets for wiring faults and verifies GFCI/AFCI protection. Easy to use and gives clear indicator lights; great for DIY home electrical checks.
