Very impressed with quality
Size: 2 Gauge Cable, Color: 20 ft Black
Quality, pliable and exactly what I was hoping for. I used it for a remote negative terminal kill switch. I have a C10 and Ran the cable from the negative terminal into the cab to a 12-volt kill switch and then back out of the cab to a ground on the frame.
I would definitely recommend the cable and use it again.

Will buy again
Size: 4/0 AWG 10FT Red & Black, Size: 4/0 AWG 10FT Red & Black
Excellent . Bought these to install a 5000 watt inverter . Arrived a little late but these cables are exactly as described. I needed 10 ft but ended up using like 9 ft. These are extremely flexible and of very good quality . Highly recommended and will buy again

Poor quality and false advertising in size
Size: 4/0 AWG 10FT Red & Black
A complete fraud. I ordered 4/0 but got 4 gauge. The description & picture was correct, but someone doesn’t know the difference in 4 gauge and 4/0. AND the jacket insulation was cheap and translucent, not solid color and supple/flexible. Poor product quality and completely misleading.
