It'll protect your secrets from your kid sister, unless she's smarter than that.
Looks cool, though.

Well, it's probably more secure than a lot of crypto-USB devices out there... :-)
Eh, looks like it's intended to be a toy, more or less. Unlike some of the other snake oil products.

You seriously underestimate the enigma.
The enigma is worth reading about. It was seriously strong cryptography which was for the most part only broken because operators were not careful how it was used, or what messages they sent (but that is not the fault of the operators, but a reflection in the belief that the technology would provide all the security required). Sound familiar today?
and of course if anyone was wondering, there are free enigma machines on iPhone... cool!
I have wanted a GPG/PGP iPhone app for some time. It'd be nice....
The site claims a keyspace of a whopping 2700 items, but it looks like each of the 3 rings is a simple substitution cipher on a 30-character alphabet, which gives them 3 x 30 = 90 possible keys. Quick - somebody go post an IACR ePrint exposing this heinous fraud!
Looks like a good way to generate those annoying 8-12 digit codes Windblows "security" function keeps demanding I create...
