My brother always picks on me but now he never does becuase of this app. Anyone I see in the park picking on me, I pull this out, and watch them look around! I tried this on my self and I hear the sound, but I think there is a speaker all around my head! But if you overdo, what I didn't do with my brother, then the victim will lose his high-frequency hearing, and It won't work ever again!

Awsome

When I first downloaded it, I didn't know what it really was. I hit activate, and then the buzz came, and I kept waiting for an explosion. Hehe, silly me. Great app.
