Works great, just like any other pen 
Works pretty much exactly how I expected it to. I could see this being useful in emergency situations where you don't have a pen or pencil on hand to write down notes. I'm mainly using it for informal notes when I'm out and about. Tiny enough to just keep on your keychain and just forget about until you need it.
