Gardner Bender GRT-3500 Outlet Receptacle Tester & Circuit Analyzer, Indicates 5 Wiring Errors, Easy Read Chart, Comfort Grip, 120 VAC , Black

Does what its supposed to but I notice it has difficulty with certain outlets I couldnt get it to fit a recessed outlet I installed even though it was small enough I didnt contact the sides

Easy to use, not easy to read some of the lights

Quick read on an electrical socket if ever in doubt. The LEDs (see product picture) tell the rest of the story. So easy to use!

The unit works well and appears to be well-made. But I deducted one star because, as other reviewers have reported, the label does not clearly distinguish between on (yellow) and off (white) indicators. Indeed, when I first used the unit, I thought it was not working correctly. There is, however, a quick and easy fix -- just take a black marker and black out the off (white) indicators on the label. After doing so, the unit is a good addition to my toolbox.

This is good for a quick basic check of your outlets. Lights are easy to see and the reference guide to the meanings of the lights is right on the device. It was able to accurately detect an issue I had with some old wiring. Depending on your issue you may still need a multimeter and/or a licensed electrician.

Seems cheaply made but it works.

Works as expected Very simple to use and easy to understand

Excelente and a good price

I have tried other products and did not get what I was looking for this product is very accurate

Straight forward to use. Does what its supposed to do.
