I'm sure if something noteworthy ever developed I wouldn't have trouble getting it replaced.
This sort of thing almost always seems much bigger when you read about it on the internet. Poor Apple, they do have a vocal lot! But that's a good thing in a sense... makes for much better products. Other companies can roll out entire shipments with flaws without even a hint of complaint on the internet.
My chargers have no cracks too... all who-knows-how-many of them.
My condolences in regard to your lack of personality!
