Works perfectly. Good fit at both ends for car and trailer end, and gives that extra couple inches of wire I needed to reach the plug.. Wire and connector are heavier-duty than I have come to expect, and seems pretty durable. Very glad I bought this!

I cut this in half to repair the car side of my trailer wire. The only thing I don't like is the mesh around the wires. When you cut this, the mesh splays out and can be unwieldy. Overall, this is a decent quality wire that does the job just fine.

Use these on glass surfaces. They are fantastic.

Both plug ends of my cable are snug and waterproof. I haven't observed any oxidation forming in the mating parts after months of use. The trailer taillights are bright as expected. If you have a taller truck, buy 1 or 2 of these to extend the trailer plug up to your receptacle, as they can be daisy chained together to make the connection secure, especially when you turn.

Good quality and just long enough to work on my small trailer and big truck .

Works great for connecting LED bars on a pickup with just a few inches too short of a harness.

It's much easier to hook up trailer lights

Disappointed that the caps are all but useless. Wound up packing pins with dielectric grease and zip tying caps on when not in use.
