Southwire 40022S Receptacle Tester; Black

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.

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.

Excellent high quality product with LED table which makes it crystal clear on whether your GFCI outlet is functional or has any issues. Definitely a bargain at the sale price.

This product has worked every time I needed it to. Great for testing GFCI outlets. Came in handy when troubleshooting a wiring issue on an electric scissor lift. I thought the wiring to the platform for AC voltage was faulted. Turned out my known good extension cord was cut internally and did not have a ground. The tester showed this immediately. Then I verified with a meter. I also use this for rental generators to verify a voltage output and test GFCI functionality. Works awesome for a quick check.

Easy to read. Works well

The lights dont illuminate very much so it can be hard to read it outside. Other than that I have no complaints

very god product and easy to use.
