    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.

    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.

    Durable, very nice wiring harness.
    Size: 50ft, Style: 6C-18AWG
    I am updating an emergency vehicle and am using this to run the equipment. It’s easy to work with and good thick wire. Came with nice little Velcro straps for keeping the roll together. The finish is nice on the outer casing. Nice gloss black. Excellent product. In fact I bought another 50 foot roll. And the prices for this is extremely good. Glad I found this wiring.
