    Disclaimer to the feedback. The sites navigation could be clearer and more intuitive and my experience was somewhat seamless this time because I've had already been to this site when pricing the cable. But when compared to a first time newcomer trying to navigate the site?... yeah there's room for improvement

    Easy to navigate and a lot of information is provided on the 12V-2x6 cable, right down to the terminals used. No other company is doing this amount of details on their cables.

    So glad the part was available. I couldn't find it anywhere else, and the price was way better than I expected, considering.
