Wire is true to specs, nice and heavy as it should be as it’s ofc copper. Used it in my distribution block to run to amps. Great wiring all around would buy again

These cables are pure copper and true to size. The insulation is thick enough to protect the conductor but still very flexible. I think we this price for OFC, you won't find a better price.

Flexible, solders easily, insulation seems good and has good electrical properties. Made ground cables for the car, cut, crimped and soldered the ends on for max power transfer without heat. The insulation seems pretty good and withstands a good amount of heat. The cable itself can transfer some power without problem. Very easy to route anywhere I needed it to go. As good as it gets for heavier cables that look decent and like OEM. The only thing I will say that is a slight negative is I dont think this is the cable itself seems a bit thin for 4 gauge. The copper calble seems to be less of a diameter than what I would expect 4 gauge but in all fairness I did not actually measure it. I would buy it again, it does work well, it does the job I need it to do and looks good. I can recommend this for projects that need doing.

In upgrading the electrical system on my small towable pop-up camper, I decided that I needed to add at least one bus bar and battery isolation switch AND also make sure the emergency brake system had power at all times. All that meant that I would need some additional wire on the negative side that could handle my load. 8 AWG was exactly what I needed. This wire handles well: easy to bend, route, strip, and terminate.
