I don’t have first-hand experience in Chinese factories, but I have a friend who works in a US factory. The quality of the items I get from Temu seem about on par with the factory rejects I’ve gotten from him.
I usually see higher quality stuff when buying from Alibaba directly, so I assumed AliExpress and Temu are their version of an outlet store. 🤷
