KAIWEETS Outlet Tester Electrical GFCI Receptacle Detector with LCD Display, 3 Prong 120V AC Voltage Socket Checker, 6 Visual Indication/Wiring Legend for Home

Dead batteries. But other than that is works as advertised.

Started wiring at home and this is a must have to check correct wiring.

Can only be used with 120 volt outlets. Even though it will read 250 volts. Will not work with a 240 volt outlet. The blade direction only goes into a 15/20 amp 120 volt outlet. Easy to use.

The tester is nice. If you want to monitor or check voltage level, polarity and grounding. Design wise I would rather have green or amber lights for correct wiring and Red LEDs for incorrect or problem configuration. When you see the red I think problem but dont get me wrong, works well. Small improvement.

The volt meter portion of the device is off by about seven volts for 120 volt power as compared to a calibrated volt meter. It works but accuracy is not good. I have an older unit with less features, but it is very accurate with the voltage reading.

Im A Electrician, & Use These Tools All Day Long In The Residential/Commercial Areas Of My Field, Voltage Read Out On Pin Plug Is Pretty Cool & Seems To Be Pretty Accurate & The NCV Beeper/Tester Is So Far Pretty Accurate As Well, Im Normally Buying Klein, Fluke, Greenlee, Ideal, Electrical Testers, But I Read The Reviews On This Device From Other Electricians That Gave It A Try As Well & Were Very Happy With This Product, Used It Today, So Far So Good, Not Bad Price Point For Both The Pin Plug & NCV Tester/Beeper!!

Well priced piece of kit. Laser difficult to see outside in sunshine. Excellent for indoor use. Works well. Good value for money

I bought this along with a 30A adapter to check power at RV sites before plugging in. I also used it to check outlets in my house that have been put in after the house was built. To my surprise it found a couple of incorrectly installed outlets and they were immediately remedied. Very happy I bought this and even though there are less expensive options, the digital voltage readout is worth the extra money.

This was an inexpensive quick check for plug-ins. The display is easy to use. I have not checked the voltage read out against another volt meter for accuracy, but the three light system for checking polarity and ground was the reason I bought it for. GFCI function seems to work fine.
