Accurate, easy.
It did what it was supposed to very well. As some other reviewers noted, it only goes in upside down on some GM trucks but fortunately I had enough slack in the wires to leave the plug outside of the bumper while I tested, otherwise you're on your back on the pavement while someone is applying those reverse lights as compared to more expensive testers that swivel. Another option might be to put a small mirror on the bumper underneath it, but I didn't have to - it worked perfectly.

Trailer circuit tester
Works great. Nice to have both 7 pin and 4 pin testing available. Super easy to use, easy to read. Always check your trailer circuits to make sure everything is functioning properly. Use this almost daily at work.

Works but…
Worked great to confirm my issue was at the trailer and not the vehicle. Only problem was when I plugged in to my 2019 F150, the indicator lights are on the underside so I had to get on the ground to see if it was working

Not compatible with Redarc brake controller
Solid, well-made. However, does not work as a tester for Redarc brake controllers. I have the Tow-Pro Elite. This tester does not work as a trailer substitute. I had to use an automotive electrical tester to provide the load instead.
