Casey Hopkins, from Elevation Lab (makers of quite a few products I really like), has posted a blog about how Amazon is complicit in helping promote counterfeiters:

When someone goes to the lengths of making counterfeits of your products, it’s at least a sign you’re doing something right. And it deserves a minute of flattery.

But when Chinese counterfeiters tool up and make copies of your product, send that inventory to Amazon, then overtake the real product’s buy box by auto-lowering the price – it’s a real problem. Customers are unknowingly buying crap versions of the product, while both Amazon and the scammers are profiting, and the reputation you’ve built goes down the toilet.

I have their headphone anchor under my desk and it’s fantastic.
