This is the real deal. I have bought and used most of the gauges on my DC wiring. All copper, flexible and just a great product! Dont waste money on China knockoffs. This is quality wire: flexible & solid copper. NOT copper clad aluminum!

Muy buena calidad. Envio excelente

Premium wires used for new sound system to our boat, heavy duty, will be buying more in near future for accessories for our Polaris ranger

Like others already mentioned, this wire feels heavy, which immediately reassured me that its not copper-plated aluminum even before I opened the package and had a chance to inspect the strands. For reference, aluminum density is 2.7 g/cm3, while copper is 8.96 g/cm3. So if youre looking for a real copper wire, this is the one. Buy with confidence and you will be amazed with the quality.

Good merchandise, as advertised, well packaged, timely shipping.....

I used this wire to make battery/starter cables for a 7500 watt emergency, it does this job without getting hot and the starter turns the engine over effortlessly.
