I purchased this outlet tester to check that my GFCI plug was functioning correctly and tripping as expected. It not only confirmed that, but it also revealed that I had accidentally wired the outlet with the load and neutral reversed! This tester is incredibly useful—it detects issues like missing ground, reverse polarity, and incorrect hot-wire configurations, while also showing when everything is wired correctly. It's a great value and a must-have tool for anyone who does occasional electrical work. If you're like me and don’t always remember the wiring details, especially for more complex setups, this tester will save you time and frustration.

This has been a valuable addition to my home maintenance toolkit. The device is compact and easy to use, with clear instructions that made it simple to test all the outlets in my home.I found a couple of outlets that were wired incorrectly, which I was able to rectify thanks to this tester. The readability of the results is excellent, with distinct lights indicating the status of the wiring. It’s reassuring to know that my electrical sockets are now safe and correctly wired.While the tester is generally reliable, I did find an outlet that was ungrounded, and the device didn’t indicate this.. However, this was a minor issue, and the tester worked flawlessly for the rest of my home.Overall the tester is a great first reference for anyone looking to ensure the safety of their home’s electrical system. It’s a must-have for DIY enthusiasts and homeowners alike.I hope this review helps! If you’re considering purchasing this product, it seems to have a strong reputation among users for its ease of use and effectiveness.

Easy to use, easy to read and very rugged. A little more expensive than the no-name versions of similar products but the build quality makes the small additional cost worth it.

So having just replaced a flaky since we moved in over 20 years ago gfci receptacle in the garage (due to loose wire, but also it turns out due to the top plug-in failed when the plug was plugged all the way in), I wanted to be sure everything is now okey-dokey out there. And it is (checked all the plugs inside the garage and outside). Before that I had also tested all the plugs in the master bathroom (aok) and in the kitchen (aok).Also unfortunately I had tested the guest bathroom plugs. It turns out the only (2-plug) receptacle in there did ground fault when tested, but there is no reset button… so now there are no usable plugs in the guest bathroom. At least the lights and fan in there still work. And in this adjacent bedroom I am in, which shares the same circuit breaker, or so I thought. Hmm… where oh where is the reset button (or breaker (nothing looks amiss in the breaker box))?Edit: Following up, I found out that the guest bathroom and the master bathroom (and all the house's exterior plugs) are all tied to the one gfci plug set in the master bathroom. Also figured out what the two kitchen gfci plug sets were tied to circuit breaker wise, and which other plugs went with which gfci plug (not all of the kitchen plugs it turns out are tied to either of the two gfci plugs). So my mapping of all the plugs and light switches for the entire house is now (even more) complete, helped along by knowing which ones are protected from ground faults and which are not. Great investment. I feel a lot safer.

No sé que tan correcto sea , cada enchufe de la casa incluso regulador ,extensiones y supresor de picos todos los marca como neutro invertido con lÃnea osea rojo y naranja en medio. No se si toda la instalación eléctrica está mal o el aparato no funciona :/ veré en otras casas y locales si da otro resultado o no
