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

Performs well at checking receptacles for correct installations.

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.

I used a Gold Marker Pen to mark all of the Dark Orange dots on the label to a Gold Color. No way - for me - to quickly spot the difference between red dots and dark orange dots. Message to the manufacturer: please use “a light yellow color” instead of the dark orange color.

it works good, easy to use n easy to read

Easy to use

The unit itself is easy to use once you figure out how to read the indicator lights on it. Its VERY difficult to distinguish the yellow from the white colored dots on the unit. The instruction sheet inside the package is equally difficult to distinguish the gray from the white colored dots.

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!

Easy to use. Little uncomfortable to hold.

When I first looked at this tester in hand I did not understand why the label legend only showed red and white indications. I had to use an infrared light to see which indicators on the label were supposed to be yellow. I have normal color vision. The yellow color is printed too lightly to discriminate it from the white indicator legends. It looks like several other brands of tester sold here at Amazon have the same kind of label. The yellow color shows up fine in the product photo but not so well in real life. Putting that aside, the tester seems well made. The GFCI test function works fine. The prongs are a bit thicker than they should be and the tester does not want to plug in without exerting a bit more pressure than for most plugs. The prongs, even the ground prong, are solid metal. I will find a yellow marker or something similar to try and touch up these faded little yellow symbols. It is disappointing that an otherwise fine product is marred by this sort of manufacturer carelessness. If this problem is not an issue for you, I recommend this tester. Its cheaper than most and built very solidly. I want to be able to understand at a glance what the lights are telling me. Ill be returning this and getting the more expensive (but legible) Amprobe tester instead.

Font is too small. Other testers might be a better choice.
