Yeah I bought two lines when I went the other day, the copper was a lot easier to work with but the length I bought was about 2.5 inches too short. It was a lot easier to work with than the steel, there was a couple dollars more difference in the cost.

 

I was very disapionetd to discover the "copper" that was used in a zillion motor-home, camp trailer, and mobile home supply cables is some cheap **** alloy. (someone made some $ there). I had run a beefy section from my mom's batteries to her solar panels on her roof. After she died I found the "Copper" crumbling to little pieces. She likely went a long time with "sub-power", due to those folx making bank selling that "copper" cable.

Or maybe I got the only crappy piece.

I doubt they quit their shenanigans. Anyway I like the idea...., but we need to watch "them".

 

WOW! That's insane. I know to look out for anything sold as "CCA" which stands for "Copper Clad Aluminum." Almost all jumper cables are made of CCA (except really expensive ones), and now lots of Cat5 cable is made of CCA. The problem is, aluminum can't carry as much current, and it can only bend so many times before it breaks. But it shouldn't look like the picture you posted, that's just crazy!
