I first heard "Duress" - if it means that the wallet is sort of divided into 2 parts ( petty and main ) plus separate passwords and it's cold of course - super added security . Don't some of them already have that ? I'm not sure about Cold or Passport, I've seen one somewhere.

I don't know what that is, so I have no opinion.

Have a read.. it's good to learn

I have not heard of it or used so I’m not sure

I think like you're saying, they are moot of you have a good security set up.
