After chatting with a Missoula County [deputy] sheriff, I bought three PepperBlaster II devices — one for me, one for my friend, and one to tryout to determine whether I wasted a lot of money.

They work. They are loud. They have significant precision delivering two distinct pepper payloads. The city of Missoula has no restriction or "issue" with the device when it is carried concealed.

They have a profile that "the other guy" might perceive as being a gun. And this benefit could reduce the confrontation, allowing me and "the other guy" to walk away.
