The item is a good tester for install of a 7 pin towing harness.

Worked as expected and to negate other reviewer's comments, there are instructions included on how to flip the display so it can be read, even if upside down initially.

Accurate description, fast delivery, works as advertised. For my 2019 GMC the display was pointed at the ground when plugged in, so I dutifully crawled under the truck to read it. The seller wrote me to let me know that I could loosen the screw on the unit to rotate the display 180 degrees, and so read it properly from above. Humbled, I can report that is true. Thank you to the seller for the follow-up.

It is just what i needed to check my RV lights, but why did they mount the light indicator on the bottom. I had to get a mirror to read it or lay on my back.

Works ok to test tow vehicle trailer wiring. It should be pretty obvious from the pictures posted what this tester is used to test however their description is rather confusing since it mentions trailer several times and not tow vehicle. The indicator lights are rather small and hard to see in direct sunlight.
