I believe I've heard of electrical fires from counterfeit electronics that had fake UL and/or CE stickers on it.

Amazon is being promiscuous. They don't appear to care where the product came from, as long as its cheap. There are almost no categories where a 'too good to be true' price doesn't mean something illegal was going on. Either those aren't real products, they were stolen (how is it we never talk about that scenario), or someone made a huge mistake and is reselling them at a loss.

Only one of those is good for news for consumers, and it's still predatory.
