Isn't that the biggest failure of Apple? I think the original Anker Powerline cable were good, but not great. The Powerline II was perfect. And it was only a small changes in material and design, it doesn't even break. ( The Powerline has slightly longer "tail" at the end of the plug so it doesn't take as much strain )
If Apple Engineers are not using its own Apple products than there is something very wrong.
In fact, our team time after time received a huge shipments of Anker cables (think 1000-2000 cables in their retail boxes)
