Southwire 40022S Receptacle Tester; Black

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

Easy to read. Works well

Works properly.

Works the same as they always do and did, including the flaw that wont correctly identify a dangerous condition. Look up reverse polarity bootleg and youll see what Im talking about.

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

Apart from lights not being very bright in a sunny room, it works very well.

Bought a house with a few bad and improperly grounded outlets, so this was very helpful in finding which to replace or repair. Several outlets were installed with the ground pin up, and this tester has the bottom labeled so this can be used in either direction without having to do mental gymnastics.

Worked as promised to check the wiring of a gfi outlet and to test the ground fault mechanism.

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.

Works as advertised!
