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

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.

I used this tool to replace an outlet that went bad. It’s good for occasional use but I would want it in my tool bag everyday. It’s not really sturdy, but it does what it’s made to do. It’s accurate and relatively easy to use. Just make sure you have the manual out it you haven’t used one before.

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.

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.

Everything Okay

-- so if youre doing your own house-wiring or a job with GFI breakers in the panel, this will check your work.
