Im also pretty hard on lightning cables. Ive been using the Zero Lemon cables off amazon. They are braided and they have stainless connectors. they come in several different lengths and come with a lifetime guarantee.

Says two warranty not lifetime. Also why are the braided ones not shipped by zerolemon?
