welcome to the forum leilp
if you think its worth a try , why not ?
let us know how it goes
my opinion of these sorts of devices is they ar e probably easily broken with old fashioned tech..
say for example the feds raid you and want to know whats on your computer
they would just get your key off you
by using thumbscrews on you
so you tell them where it is
but seriously..
if you want protect your data from prying eyes when you are not at your computer
it would be fantastic
otherwise i dont see much use for it..
