Reasonable substitute for real copper wire
Color: 40FT Wire+40FT Cable Sleeve
Nice cable set. This will be very handy when I install my inverter in my camper van. While I don't really like the idea of copper clad aluminum (it's cheaper than 100% copper) as long as it doesn't wiggle around much, it'll work just fine. The crimp connectors are great- not as heavy as I would like but they will do the job. Overall, an OK thing to buy

Nice wiring kit with CCA wire.
Color: 40FT Wire+40FT Cable Sleeve, Color: 40FT Wire+40FT Cable Sleeve
This is a nice kit with a lot everything you need to wire up your project. This is CCA wire, so make sure you use it in the proper way. It will not take as much amperage over as long of distance as OFC wire will. The wire itself is good quality. It is true 0AWG and quite flexible making it easy to route through your project. The lugs crimp easily and hold well. The split look wire protector it nice quality and works well. The tool supplied to insert wires into the split loom is amazing. I have never used a toll like that and it works so slick.

Don’t use for automotive
Color: 40FT Wire+40FT Cable Sleeve
Don’t get me wrong it’s not a horrible product but these wires have an extreme amount of resistance to them, and once they get hot they drop voltage drastically. It was nice it came with a bunch of eyelets and made it easy to assemble but unfortunately once they were over 100F temp (live in Florida so cars get way hotter than that on the inside) the voltage would go from a normal 12.5-13.5v all the way down to 8v. Partially my fault I did not notice they were CCA wire instead description, would not recommend for automotive use.

Works as intended
Size: 1-Female to 2-Male Y-Adapter-1 ft
What can I say? Works as intended. Seems pretty decent in quality and has a decent thickness to it! Fits pretty tightly so you don't have to worry about sloppy RCA connections.
