The keylogger was designed to be placed between a keyboard and the device the keyboard is connected to. And that's what all the product text, instructions, example pictures, and demo videos show. Think of it kind of like the Key Croc, except without leaving a visible adapter in the connection path. The keylogger version of the OMG Cable has been quite a bit more popular than the nonkeylogger version. So, you'll probably find other customers who are willing to share some of their use-cases in the chat channels.
