This is a comparison of YubiKey 5C NFC currently available for $55 https://smile.amazon.com/gp/product/B08DHL1YDL/
and Feitian ePass K40 currently available for $26 https://smile.amazon.com/gp/product/B089ZYVCV6/
They Yubikey has better software, thinner and 1g lighter hardware, and support for a lot more advanced security key features like SmartCard PIV etc.
The Feitian ePass, on the other hand, has tacky software (Windows Only, see screenshot), sparse documentation and a subset of the features that Yubikey has.
The Feitian is less than half the price though! If you want FIDO and FIDO U2F to secure your usual online accounts like Google, Lastpass, 1Password, Facebook, Dropbox etc, then the Feitian will do just fine.
As for security vetting, since Google uses Feitian and Yubikey both as vendors for their own Titan security keys, there's a reasonable assumption that these two companies passed Google's tight security bar.
