I'm pretty pumped up to get USB C to Lightning cables from Anker just having bought an iPhone. I got 3 3' cables from another supplier for cheaper than what Apple charges for one, but generally I'd prefer something from a company I know isn't going to ass up my wiring and make my phone/tablet/etc no longer function. As is, the companies that make great third party stuff under MFI certification program aren't making them.
If you're in a Best Buy you probably shouldn't be on slashdot.
