Like I said, if any of the chargers or cords I have received from Amazon are counterfeit, they're good enough counterfeits that I don't care. My iPhone, iPad, and MBP all charge just fine, still have perfectly fine working batteries, have never had any issues with the electronics, and nothing has caught on fire after years of use. The headphones I've bought from Amazon sound great and have given me no issues. The lightbulbs I bought from Amazon light up my room just fine and last a long time. The SSD I bought is blazing fast and has plenty of space (confirmed by multiple diagnostic checks). The clothes I have bought are comfortable and fit well... And if any of these things weren't true, I am confident it would take me extremely minimal effort to return the item to Amazon and buy a replacement.

Obviously counterfeiting is a problem and in an ideal world there would be no counterfeiting at all, but I remain unconvinced that it's something I have to worry about materially affecting my experience as a customer buying stuff from Amazon.
