does anyone uses a Duress PIN or decoy wallet?

I was wondering if anyone uses a Duress PIN and if yes - do you think of it as a good feature? have you ever been in a situation where you had to use it

also how much do you put in the decoy wallet? too little might be suspicious, too much and you lose money

(disclaimer: I work with r/keycard_tech - this is a general question and I’d like to know more)
