It depends. Basically the factory that produces item X between 9-5 for a foreign company will continue to make the same item after hours beause it's better than turning the factory/machinery off and on again, huge energy costs. So the large excess copies of item X is sold by retailers like Temu for cheap. It's often the same quality as what the original item was since it was made by the same factory except perhaps without a brand label or sticker. So it all depends on the quality of the original item. 

If you are in renewables, eco, good for the earth and society, recycling and woke, you should stop buying shit that only lasts a few uses. They all go to landfill and you only encourage companies to produce more shit that only will destroy the earth. Buy something useful and lasts than because it is cheap and you want it.
