True copper battery cables that are high quality
Size: 10ft, Color: 4awg
I love having heavy duty cable on hand for my cars. It's so nice to be able to make your own starter and alternator cables when restoring cars.
These cables are 100% copper, not CCA (copper clad aluminum) like many others are. Copper is far superior for conductivity and handling higher loads.
The rubber on the cable is thick and yet very flexible..it's clearly marked and seems very durable. I like to use a hydraulic crimping tool and then add marine grade heat shrink tubing with the adhesive inside of it to keep it as weatherproof as possible.

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.

Well made, a solid connection.
Size: 6 Pairs / 12 pcs
I liked them. They really lock down on the speaker wire to make a firm connection. They seem well made and are easy to install. My system sounds great.

Works as intended
Size: 12 Pairs / 24 pcs
These banana plugs are quite easy to use, and securely connected my speaker cables to the receiver. They have a quality feel as well.
