    All was great, shipping is just really expensive to go above standard and the standard wait time is pretty long. Understandable for sure but not a quick ship unless I want to pay astronomical prices for a cable. Shipping is more than the cable itself.

    I think this kind of poll should be shown after order is completed -- I can't say if I'd buy again if I had not received the product yet :) Other than that the website looks a little dated, but it serves its purpose well. Keep it up!

    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!
