I had moaned and groaned about the same situation on this forum years ago. I always treated my Apple cables with the utmost respect, never yanking or folding them. The consensus was that the off brand cables were generally as bad as Apple’s, often worse. The only exception was very good advice from some TidBITS Talkers about Anker’s Powerline cables. In my opinion, they are longer lasting. It was a very good recommendation, and I’ve become a big fan of Powerline cables, as well as their ultra fast chargers.
But I feel obligated to say that we’ve been using our AirPort Extreme since 2-3 months after they were first released. Our SE 30, ancient iPods, Cheese Grater, Power Mac 9300, ancient MacBook Pros, and iPhone 4Ses are all operable. So are our ancient keyboards. I think that’s a very good testimonial for Apple hardware, especially since our MacBook Pros did take a lot of hard knocks when we needed to drag them around on public transportation. IMHO, the cables’ survival rate isn’t any worse than other knockoff brands, except for Anker.
