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

Font is too small. Other testers might be a better choice.

I inspect apartments and houses for NJ state housing and this tells me if a unit will fail for wiriing issues

Some receptacles are installed upside down which make the unit hard to use & read.

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

The price is great. However, the two flat prongs are not properly aligned when the unit is viewed from the side. Consequently, the unit is very difficult, and in some cases impossible, to insert in to some outlets. The first unit I received was exchanged due to this issue and the second item still had plugs that were not properly aligned, but were better. This is clearly some manufacturing (or design) error and should be addressed. However, for such a low price, its tolerable.

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

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.

Does not have a gfi button on the black version. Otherwise works well. Good buy.

Always wanted one. Works great nice to have around the house

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.
