Good value, very useful for go kart wiring
Size: 100ft, Style: 6C-18AWG
It's a good spool to have around to wire lights and things on the go karts. Also came in handy when I had to patch a bit of melted wire harness on the tail of the old Dodge.

Beware! Very thick wire
Size: 50ft, Style: 6C-18AWG
I'm not going to ding the product, because it's totally what it says it is. I didn't look at the diagrams to see that this wire is 10mm wide. Almost half an inch. Waaaay to thick for the project I needed it for.

Fair product

nice product good price, the only issue I had was the sleeve was very loose on the wires so doesn't really hold the wires in place.

Fantastic to do 1 run and power multiple loads
Size: 30ft, Style: 6C-18AWG
Great for wiring up multiple loads. In my case multiple lighting with different switches so that I can turn them on independently from one another.
