Mine had been treated very carefullly, nevertheless several of the chargers belonging to my family are showing what I would consider premature wear and tear. (Meaning they are within two years old, most of them current, left in the same place and only used to charge devices in place without any other simultaneous use. I supervise the charging myself to ensure the kids do not pull on the cords inappropriately and I am also speaking of the charging cords to my own devices, that I oversee exclusively. So there is some merit to the complaints about Apple's own products.) In my humble opinion.Don't know what you're doing with your cables but I've had mine last for ages.
However, these ripoffs are another animal entirely and I applaud any efforts to get them out of circulation. I say this as a former Note 7 owner. Apple does not need its reputation needlessly tarnished by the failings of ripoff products.
