Connection technology was good, but materials used in cable and design of strain release was horrible. Never seen a cable disintegrate without any reason after couple of years.
Funnily enough my first ever Lightning cable that came with my iPod Touch 5G is so worn out you can see the 4 wires in it. Insulation and shield are completely gone at one end but it still works fine.
Thats how fires start.
Incidentally, I have a micro USB cable that came with my Nokia N97 (must be 2012 or something).
It’s flawless still and even after more than 10 years of service (now charging my xbox controller) it’s working fine.
I’ve tried purchasing identical “original” cables of same kind since then, but they all last a few months before getting lose our stop connecting.
