Can I trust that these aren't fake? https://www.amazon.de/-/en/12Gbps-Controller-Linux-VMware-Freebsd-Default/dp/B0D49WDBVV

I did read that they are often refurbs or just removed from old server blades, but can I trust it to work? I use zfs so I'm not going to use the card's raid controller if it has any.

I have read a lot that chinks will create low quality copies but with an older HBA model like this, can it be genuine LSI?
