    No hitches, I got to feel bad about how expensive the cable is, really quickly from when I first looked for it ... I can't say anything wrong about the process itself. Site was really easy to work with

    Great website and product selection! Also the available customization options are great too! I am very excited for my new 12vhpwr premium silver wire cables to arrive! I only have one suggestion: maybe offer more cable combs for longer cables as an option... thanks for your time and great service! Have a great day!
