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

Not much to say about a GFCI tester. A little less bulky than some. Solidly built. The neon lights are easy to see from all angles. The test button trips my GFCI. The big win is the price. Some dealers sell the same thing on Amazon for 3x the price. Sometimes without the test button. Every home owner and RV owner should have one in their toolbox. Maybe more than one as they seem to disappear in the night.

Easy to use. Little uncomfortable to hold.

Fácil de usar , buena calidad y muy útil

Worked as intended - Shipped quickly

It is easy to use with good price. A quick way to make sure your GFCI plugs are still functioning.

it works good, easy to use n easy to read

It seems to work, great value for the money.

Just plug it in and you look at the lights and reference chart on the device. I wish the signal lights were a little brighter when used outdoors, but works well enough.

Easy to use and simple to understand

I have literal owned over a dozen of these. They work great, are easy to read, and most importantly are the easiest I found that insert into the TR (tamper resistant) outlets. I am a home inspector so I use this on a daily basis, so over 100 times a day 5 days a week for work. They last anywhere between 2-6 months at most. They are cheap enough but carry several in my bag since I never know when it will fail. So good for the homeowner but not so good for professional daily use.
