I don't understand who all these people are who are having bad experiences with Amazon. I only ever buy products that have the Prime label and have plenty of verified positive reviews. Stuff always arrives very quickly (often the next day), and I have literally never had a fake product mailed to me when I do this.
One time I bought a used product from Amazon and it was a little beat up but it still worked.
Another time I bought something that was clearly manufactured and sold from China, and sure enough it sucked, but I just returned it and it was no big deal.

It's possible you're not buying commonly-faked items, or possibly it happened and you just didn't notice. Lots of fakes are of similar reliability for the first 20-50% of normal lifespan.
