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

The fine print is a little hard to read. I had to use my phone as a magnifying glass.

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

Use it when you want to do a quick troubleshooting and dont want to take your multimeter out of your toolbox. It can tell you if youre wiring is ok or it has some problems which you can later on investigate more with your other tools. At this price its a must for every toolbox.

Have an old house and needed to test outlets. It works well and would buy again.

When using this product for some odd reason certain new types of outlets it will not go in and I have to literally jam it in to make it go in side the socket. I need to figure out why it keeps doing that. But overall it is a good product.

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.

I think I have a tool for a lifetime . good quality

Does exactly what it is supposed to do, used it to check the rewire of my house after my little brother gave me a hand... Im glad I did.

Does exactly what I needed it to. Check to see if an outlet is active and wired correctly. Does a great job and is a compact item to handle the job.
