These days you want a unique way to display important messages. Something quiet but easily seen. The programmable scrolly LED badge is just the thing. It’s a pocket-sized gadget that goes with you anywhere. You can store up to 6 messages, one of which can have up tp 512 characters and the rest can have up to 256 characters.
That should be more then enough capacity to tell those around you anything you want. I would recommend sitting in the front of a crowded movie theater and letting those behind you know just what you think about the steaming pile on the screen. As you can see from the picture, it’s a belt buckle too.
