So, I've seen some reviews about light bleeding from one light to another, giving a somewhat confusing reading. This isn't light just bleeding through plastic, the bulbs in there are indeed lighting up but very faintly. I rewired a bunch of outlets, and in the process learned a few things about this device:
-It's made very nice, feels good
-It Cannot diagnose every problem
-The chart does Not describe every possible indication you may see
-It Does let you know overall if something is wrong.
So, what i mean is that on the device it shows you a list of all possible light configurations. However, two situations are notably missing: all lights on, lights partially on. I've encountered situations where all lights illuminate, but the chart doesn't show this situation. I've also seen variations of lights being on, but only slightly. This is where i think some folks thought it was due to one bright light bleeding into the next light making it seem like it might be on, but it's really an indicator of some other issue. Either way, unless you get two solid orange lights, something isn't right.
You might think that they would mention this in the manual. Nope. Nothing. That's really unacceptable for a device intended for electrical work.
Overall, this device indicates two things reliably: Everything is OK, or something is Wrong. If you get anything but two solid orange lights, something to some extent is wrong. Even if i get solid light indications, i check everything again with a multimeter. You can get decent ones for around $25, and they will tell you exactly what's going on with the outlet. Why not just get a multimeter? That's certainly an option, but my preference is to have the little tester for blanket sweep checks of everything, marking the bad outlets, then going back and checking the bad ones with the multimeter to see exactly what's going on.
Bonus round:
Testing an outlet with a multimeter is easy: set it to voltage reading and: red probe to the (hot)small outlet slit, black to the (neutral)big slit. should be 120(ish) volts, then do red to small slit, black to ground (bottom outlet hole), should also be 120v. Then one probe to big slit, the other to ground, should be zero or near zero reading.

In many old houses, the ground connection is either disconnected or connected to a poor ground source, like a screw that may not be truly grounded. These lights allow you to visually see how good the ground connection is when compared to the normal L-N (Line to Neutral) connection, so if the third light is dimmer, then the L-G (Line to Ground) connection is most likely faulty (it probably will not be able to carry the same amount of current that would be required to trip a device or to carry power surges to ground).
In the pictures I have attached, you can see I have two weak ground outlets, each with a different 3rd light intensity. On the first one where the third light is almost extinguished, the AC voltage between L-G is 46.66V AC. The other outlet tested had a more lit third light that is still dim, but you can see that it registered a slightly higher L-G voltage of 97.1V AC. This is still not up to par with the normal L-N voltage, which should come around 120V (standard US AC voltage). As you can see, the lights allow you to quickly visualize any ground faults without busting out a multimeter and sticking multimeter probes into live outlets.
If you are testing outlets often, a non-contact voltage pen tester may also be a worthy investment. Although you are not able to test L-G using this method, it offers a quick and easy way to test which side is live without even plugging anything in. The one I have allows for an intensity reading and reads red on the right side (hot), while the neutral side reads green. This corresponds to the reading of the outlet tester (short side = hot, long side = neutral).
The GFCI test button works well, and you can see that it was able to trip my built-in GFCI just fine. I find that this type of testing to be more practical rather than just relying on the Test button on the GFCI itself. You can also see that that outlet (which is properly wired), has the same light intensity for both the 2nd and 3rd light.
I am very happy with this purchase. No complaints about it so far.

This is the perfect tool for this.
It’s so easy to use: just plug it in, check the lights, read the helper guide on the tool that matches the light and voila, you know the status of your outlet.
The plus: you can test the GCFI receptacles to make sure they are secured and work as intended.


Excellent buy!
