Hard to read.
If you own a prewired Ford 150 of a new model the units have to be installed upside down in order to work. Makes it VERY hard to use!Delivery was quick and accurate. Score strictly about difficulty of use.

Works just like it was designed to
Needed to check my trailer wiring on my Dodge truck and this is the fastest and most reliable way to do that. Sure there are other ways to check the wiring but this is the fastest way without having a trailer hooked up. Worth every penny it cost which wasn't very much.

Works
Works well. Tested my truck lights. Not sure if it a product issue or truck issue but the lights are on the bottom making it inconvenient to test the connection. 18 Silverado tow package from dealer if it makes a difference.

If you have a trailer with lights, get one.
I do seasonal and infrequent towing. I bought a new jeep with towing package, waited too long to use it and had no trailer lights or brakes. Chyrsler wouldn't or couldn't fix it. Another time, after a $1000 repair, hooked up, no lights, dropped vehicle off to shop only to get a call that the Jeep was fine. They used one of these. Having one would have saved me a lot of time and money. Fast shipping, pro package.

Great Troubleshooting Tool
Wonderful tool to troubleshoot my trailer light connector on my truck. It helped a lot to solve the issues of blown fuses.

Wouldn’t work on my truck.
I have a GMC 2500HD with factory trailering connectors. For whatever reason, the 7 wire would not light up and the female connector on the flat four was on the wrong side so I would have to lay on the cement and look up to see the LEDs. Too bad, I really wanted these to work.
