From a quick search (says “Apple Computer”, but tell me if that’s really made by Apple or not): https://www.amazon.com/gp/aw/d/B0787CFNRQ/ref=mp_s_a_1_3?ie=...

If you buy something used, or something with a lot of knockoffs (Xiaomi) or old tech (GameCube Controllers) there is a chance you will get a counterfeit.
I switched to buying all that stuff from eBay and it's much better. Untrusted-by-default makes eBay a very healthy marketplace to buy and sell in.
Then within the last year I've started receiving probably one out of five products being very blatant fakes. I only order Prime items and only sold from the manufacturer and only brand name, but I still get counterfeit items. It's actually driven me back to retail stores for items where I 100% need to get the real thing.
I buy everything on Amazon, and I've never had this problem. Do you have any data to back up this claim?
