As a past poster said, it’s pretty much exactly the same stuff that you can buy on Amazon but cheaper.
I suspect many saying ‘Cheap tat’ haven’t actually used Temu. I have had some amazing bargains from trailer accessories to garden lamps. I haven’t bought one single thing that has been crap quality and only one item took longer than a week to arrive ( and that’s because I missed that it was coming by land.)
It actually shows just how much mark up other online stores are putting on these goods and I can imagine that NONE of that markup is going to the workers making the goods.
