Let’s start with a legal disclaimer. You should never try or test this, ever. Not until the zombies are stumbling around and you need to escape from your families hardware store and need to kill a few walkers very silently.
So again, don’t try this, it’s illegal.
Now on to regular business. How awesome is this guy? I’m not sure how long the baffles last in this type of unit, but you would surely be better off with it than without it if you needed to escape down a walker infested street.
