I received my SOUND GRENADE+ from Caltopia and just put it along with my keychain as decoration and it totally save me!!!
I got out of Bart at ~11PM and when I was walking towards my car (I was around 100 feet away from my car), two men approached me and ask me for my money and claimed that they have gun. I immediately pull the SOUND GRENADE+and they ran away!!!! I cannot believe it!! I didn't expect to use it when I first got it but now I am definitely going to order one or two more as backup!!!
You guys are awesomee!
Thanks so much,
