Summary
This explosive can blind zombies and survivors for a few seconds. It's underestimated by most, as you can use it to basically render Brutes useless, make a Leaper become totally confused, or make your escape away from a horde of zombies.

The military distributes them nowadays to give survivors an easy way to escape from zombies, temporarily blinding them and also deafening them. Sadly, however, most survivors say they're useless. Don't worry, you can't hurt its' feelings.
