You have to be very careful on TEMU. My wife has been getting a lot of fake items lured by the low costs. Recently some of those fake silver bars and jewelry.
ebay has pretty much shut me out as I run a VPN and they want verification methods that I cannot provide, after 27 years of the bay I'm also done. I bought from alibaba or aliexpress one of the 2, and got a stereo switch, amp or speaker, that the left and right channel was crossed over internally...drove me nuts.
Amazon has some issues, but with Prime the free shipping and free returns make it a better option for us. I resisted Amazon for a long time and used them sparingly, but they seem the better option these days.
As far as India, I just don't trust too much from them. Weren't they responsible for the fake eye-drops that killed a bunch of people? I saw a documentary about them making backyard, back alley fake pharmaceuticals. And their metal is terrible as well...saw motor shafts tear apart on fan motors etc.
You have to be diligent these days as we, the US of A, seem to have become a dumping ground with seemingly less and less control on whats coming in. There are a ton of fake products in the marketplace. We the people are the controls, the litmus test, when we get hurt, then we pay attention.
Just sayin.
