So the problem is that Amazon is extremely non-transparent about the policy and what the triggers are, so you will never see it coming. This is exactly why it causes me so much anxiety, I've heard that if you have bad luck with one high value laptop being defective or God forbid being stolen off your porch, that can do you in. So I want to save all my social credit for actual nightmare scenarios like that rather than waste it on returning defective Chinese cables and trinkets. I also avoid buying high risk items off Amazon now. (Products I know from personal experience have a higher than 1 in 1000 defect rate.)
