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

Perfect for the added comfort of knowing all is well

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.

I ordered one and it would not insert properly into my Tamper Resistant Receptacles. I received a replacement and the same thing was true. I took a small metal file and 30 seconds on both prongs to remove any sharp angles - it now works perfectly and inserts smoothly to all of my outlets. Overall I am happy with this tester at this price but you may need to remove burrs or angles on the spurs so the shutters on a TRR open correctly.

Straight forward to use. Does what its supposed to do.

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

Performs well at checking receptacles for correct installations.

This one was one of the lowest cost outlet testers I could find. It doesnt have any fancy gadgets but it does what it is intended to do. I really dont think I will need another one since it seems sturdy enough. I am not an electrician so I cant comment on specs, but this is great for us DIY people.

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

I replaced all the outlets in my home, this guy was a life saver! Reviewers who say you cant tell the difference between white and yellow light need a tutorial on how to read the tester! Super simple, great product, great price!

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.
