Dance with China, Dance with the Devil.
This stuff is a real problem for manufacturers and consumers. To the unwitting consumer, they are buying the “real” thing at a discount. To manufacturers, Chinese knock offs can damage their brands (when things fail) or worse still get blended into legitimate supply chains thus creating liability issues that need to be worked through with costly lawyers and IP investigation teams.
Personally I’d be happy if we didn’t trade with China until they started playing by the same rules as everyone else. The planet would probably benefit from that as well.
