Amazon.com is full of drop-shipped no-name almost literal polished plastic turds from China. A few useless stock-photo level product images. No technical specifications, just the same generic terms repeated as `description`. A completely unknown brand and company name. Of course only available for a few months, so bad reviews with this product name and brand don't accumulate all over the Internet. Rinse, repeat.

It's great that they "make things right" somehow. But their marketplace is crap, they are the embodiment of a cancerous flea market that grew to enormous proportions.

The problem is, Amazon shouldn't be able to set prices so freely. Market forces don't apply when you can just dump all your profit into a new niche, obliterate the competition, capture the audience, then set prices to maximize profit, and move to the next market segment. (Just as Google's money distorts the browser market.)

(Books happen to be the segment where most of this doesn't apply, because books, like any content are not substitutable, yet copies are perfectly fungible. At best there's a very minimal concern about the condition of used books. And it shows that Amazon's whole model is built on this. One completely unknown PowerBank/USB-hub/gadget is just as good as an other.)
