Quoted from calico1997:A note about the history of this product: These were a concept I worked with and posted about roughly two years ago. Thanks for everyone's feedback! At the time, there was no way to program messages into the device without hooking up physically to a PC and installing software. But these new versions, for a reasonable cost, now include instant message programming via free smartphone app. That's what made this a viable product for the average user and why it wasn't offered until now.

Yeah I’ve bought an a bunch of these at different conventions for fun. They’re usually like $25 or something.
