Pute copper thick cover durable yet flexible, nicccccce

Good quality product

very good product and price

Ordered to relocate battery to the rear on my civic SI, after reading reviews for copper coated wire i figured real copper is the safer bet. Its only 4 gauge but its been about 3 weeks and everything has been working fine, i just added an extra layer of protection wrapping the wire in the black plastic sleeves people use for audio installation. As the title says so far so good.

Great wire. If you want to save weight on drag racing applications. You can beat this wire. I have used this in 4 builds so far.

Great for power cable on car stereo install. Very flexible true awg size. Awesome

Great item!

I used the wire to make quick release battery cables for my off road Land Rover. Have been tested intensevely and are really great, very flexibles and can cope with the heat with no problem. here in Colombia this size of wire in automotive wiring is really expensive (3-4 times more expensive).

Product seems good but too early to say how it will hold up in actual use.
