A huge amount of products are just generic Chinese products that have a brand slapped on it. If you’ve ever bought a random small USB device (i.e USB hubs, etc) from a major brand like LogiTech and others, if you crack it open it is just the same device as cheap resellers with a branded coating. It’s not worth it to many companies to bother manufacturing their own small tat so they just sub-contract out.
And sure, it likely works, but it’s the exact same hardware with the same capabilities as a product a 10th of the price.
