Let's start of by saying I work in a prison and can not have any "electronic contraband". I could actually get into more trouble bringing in a PV as opposed to real cigarettes. If I were to "hypothetically" buy something, I might consider the SD keyring but thought something that looked like an actual pen would be better. If you don't want to "hypothetically" help me break the rules I understand. I just hope I'm not breaking any forum rules as I post this. Any "hypothetical" info would be great.
