Both sticks aren't that bad when looked at from an usability standpoint, but fail at the point of security. Is there still any use for them, then? Well, perhaps as a gimmick: having a fingerprint-scanning device on you at least gives you the opportunity to start a conversation about it: the 007-like topic of biometrics always is an interesting one. For real security, the only thing that can be done safely with the stick is lock your Windows-session: a hacker can't change the software to a hacked version as long as your computer is locked. Unfortunately, if you want any non-snake-oil type of security, that's about all these sticks are good for.
I would like to thank the people from usb-secured.com for their help. First of all, they provided the sticks to us in the knowledge that their security might be broken by me. As soon as I told them that had indeed happened, and confirmed it by sending them the 'secure' contents of a second pair of USB-sticks, they acted very sportsmanlike: 'The sticks were meant to be offered to businesses and resellers. Ofcourse, we won't offer them till everything is order... which unfortunately doesn't seem to be doable in the short term. Potential customers will be informed of the (im)possibilities of the product. We'll take the advice you've given us to heart to be able to create a better-secured stick in the future.' They also told us they would put up a summary of the findings in this article on their webpage shortly.
