Anything cheaper than this is junk
Reviewed in the United States on March 5, 2017
This is the best price I found after hours of searching for 100% copper for 4 Gage cables. American-made Deka 4 gauge 20 Footers cost twice as much and both these and my Dekas start my trucks in cold weather exactly the same (however the clamps on the Dekas are slightly better). I purchased the Dekas for my ranch truck last year but they are no longer available by Amazon Prime. 4 gauge copper 20 foot jumper cables are the gold standard and Will Never Let You Down. Be careful what you buy and read the description so you don't get misled and purchase covered aluminum. Copper clad aluminum cables are just junk and it's a shame such products are even available.
