Good price on Anker's reinforced Lightning cables: 2 for $16

Why do Lightning cables fail so frequently? I don't think I've ever had a micro-USB cable malfunction, but Lightning cables go out all the time. Curse you, Apple.
The least worst Lightning cables, in my experience, are made by Anker. And these reinforced ones last the longest. The come with an 18-month warranty, which is about as long as you can expect from this generally crappy technology. Amazon has them on sale right now at $16 for a pair.
