Southwire 40022S Receptacle Tester; Black

Our LED lights flicker when the washer is running so I was worried that we might have a wiring problem. I used a multimeter on a few outlets but determining problems using a multimeter is a multi step process and Im always worried about breaking the multimeter sticking it into live sockets. This tester is so much simpler and gives immediate results. I was able to check every outlet in the house within 10 minutes. I found a few that were wired in reverse, which is an easy fix.

I like the different features and electrical checks instantly performed.

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

Very well made easy to use. Yes, highly recommended and would buy again. Really easy to view the individual lights.

Never use one of these before, but I was testing outlets in the house just to see what would happen with the different outlets and actually found an outlet where the ground was never attached when the house was built

Works exactly as advertised. Great tool for the price!

Got this to trouble shoot an outlet in our home. Works great, durable construction, and super simple to use. Just plug it in and read the lights. Legend is printed right on the device to tell you what youve got.

Easy to read. Works well

Works exactly as it should. Recommended.

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
