$5 USD. What did you expect?
Always surprises me when people pay essentially nothing for a product and then complain about quality.
Would you say the same about a vendor selling rotten or spoiled food?
I would expect at any price point the seller should not be lying about the specs.
I mean yeah you get what you pay for. The main issue I think is false advertising; there's only so much you can do for foreign webshops, but if this were on e.g. Amazon, then Amazon should be pulled up on it (that is, huge fines so they don't do it again).
EU is cracking down on foreign webshops at least, setting rules for advertising, increasing import taxes to avoid flooding the local market with many individual packages that circumvent spot checks for basic electronic safety and (EM) emissions (what the FCC looks out for as well), etc.
Marketed as a USB 2.0 hub with a single USB 3.0 port? When I last looked, typing truth via keyboards were free and valuable at the same time.
