Excellent

Electrician daily use over 1 year works as expected.

Helped me find the issue with my outlets, works great!

Works like a charm. I had one of these years ago and lost it. Glad to have one back in my electrical tool bag. Great buy and a great brand tool. If you dont have one get one. Itll save you that headache when you have wiring issues

This is designed to detect most vommon wiring problems in standard and gfci receptacles. Open ground, reverse polarity, open hot, open neutral and hot/ground reversed. Finest quality on klein tools innovate tools.

Fácil de usar y una herramienta muy útil para electricistas

So far so good, it works as intended, the GFCI test works great as well.

Gives information likr properly grounded, neutral is connected etc.

Plug and use, the lights and descriptions tell you exactly what you need to know.

Don’t bother buying. Using this device is not safe and gives false readings. Tested it against what I was getting from a voltmeter... voltmeter = good outlet, tester = open ground and failed GFI. Threw it out, didn’t even bother returning it.
