Man you know, the most infuriating thing about this to me is the fact that the "company" that branded the machine offered to give her money but required her to take down the negative Amazon review - and, honestly, I have to say I have mixed feelings about her accepting this; I'm not going to declare that it was definitely the wrong thing to do, but I'm also not really totally sure it was the right one.
But that aside, this is not a that-company problem because "Amztoy" isn't a real company. It's an Amazon problem. Amazon's business model has created this whole ecosystem where a no-name manufacturer produces these things and doesn't directly sell them to customers but instead supplies them to "companies" whose only function in the pipeline is to brand them and put them up on Amazon or Alibaba or wherever else. It's invariably cheap trash meant to be sold to people who don't know any better and the entire pipeline is designed to ensure that if enough people complain about the quality or safety of a particular product the reseller can just drop its nonsensical "brand name", adopt another, and continue selling the exact same thing. "Amztoy" may have taken that specific product page down, but as you can see in the video the same thing is being sold under countless other brand names and I guarantee you that one and most likely several of them are whoever "Amztoy" was, the exact same person or people using a different name. And of course the manufacturer, the ones most directly responsible for how dangerous or faulty the product is - well that company's name never makes it onto any of the product pages; it doesn't even have an Amazon account, so it can never face any consequences even theoretically.
On top of that Amazon sucks as a company, it doesn't vet quality, it allows companies to post fake reviews and bribe customers to write good ones, and takes down bad reviews for them; it won't take down product pages even for extremely dangerous products unless something gets on the news. It's just a complete garbage site.
