Apple does a lot of things right. But its Lightning and 30-pin cables, while sleek in design, are not very robust. I've gone through many of them as the edges get frayed. Sure, there are replacement cables and I've used many of those too. But some cases, like the OtterBox, only have a small opening, which means only an official Apple cable or the rare third-party cable will work with it. If you use an official Apple cable, but want to protect it, TUDIA is crowdfunding an adapter that acts as a stress relief for the end of an Apple cable.
