Southwire 40022S Receptacle Tester; Black

Saved the price of this unit 10 times over on the first job with GFI problems.

What can I say, it does what is supposed to do. I recommend it. One problem only: The little printed or painted squares showing the result are super little so if you dont have 20/20 vision anymore you will need your glasses. For that Im giving it 4 stars.

the test button is great! very easy to test all your GFCIs

Works exactly as advertised. Great tool for the price!

This is a good tester aside from the fact some readings may give false positives. It told me i had hot/ground reverse when i really had a missing neutral.

The unit seems to work well and identify troubled outlets and wiring issues but the test lights are not very bright to the naked eye and are even worse in a photograph. As a home inspector, this gets a lot of use but the photos dont turn out well. I have better luck with my outlet tester from Harbor Freight reading the test lights.

Got it for home inspection and it worked as expected.

Item was delivered as promised. I use this tester not only in my home but also to check the main breaker at the campsites I have visited to ensure that the polarity is correct before connecting my travel trailer to the 30 amp service. The indicator lights make it easy to verify
