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

Easy to read

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

It does what it suppose to but you need to use it with a non contact voltage detector as a 2nd tester. All these type of testers does the same thing. Some better than others and this one does a great job but none detects if the plug is a reverse bootleg (reverse polarity with the ground connected to the hot line). It will show as correct but it really isnt. Thats where you need a non contact voltage detector. A reverse bootleg will have the entire receptical electrified/hot and using a voltage detector will beep when you get close to the receptical when it should only beep when you stick it to the hot slot. If this happens call an electrican to fix it or fix it yourself if you know what you are doing.

Had a problem with electricy in garage. This tool helped fix problem.

It works.

Very easy to use and quickly tell you if you have wired an outlet correctly. a must have tool for every tool box.

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

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!

This works well, I dont have to find a lamp or toaster to find out if an outlet is getting power. I have another that is just two probes but you have to get them in correctly, mess around for a bit. This thing you just plug in and voila! (or not). I am a novice and a bit afraid of electricity. I can install fixtures, repair lamps, hookup outlets and switches, but nothing more complicated than that. I believe this is essential for homeowners. I recommend.

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.
