How to determine if a widely available NVMe SSD is too cheap in price to be genuine? [closed]

I’ve found this NVMe SSD that is just what I need to extend the storage in my current laptop (or maybe even to my next laptop).

It seems too cheap in price for the supposed manufacturer and specs, though. At ~$120, it’s fair priced to other NVMe 512GB out there. But, it’s the fact that it’s PCIe Gen4 and the manufacturer is supposedly Samsung that raises the flag.

Is the offer a little bit too good to be true? Then, it seems also that this part is prevalent in bargain stores online (eBay and such). You’d think if the product was so good it’d be sold upfront at brand stores, if not Samsung themself?

Is the product just widely faked? Am I in risk of damaging my laptop when I plug it in said laptop? Can I hold the seller responsible for the damage?

What are your thoughts?
