Mom Approved
"This is wonderful for our daughter who walks to school. It's safe, not against her school rules, and gives her some security. You just pull the top off if there is a crisis or emergency and the siren sounds and light flashes."

Dana M.

Great Peace of Mind!
Everyone needs to feel more secure. I know because a lot of people have problems with shopping and other activities. It's so easy to use that no one will know you have it. All you have to do is pull the top out from the bottom and the noise starts. It's loud enough to get someone's attention so you can get rid of the need.

Jamie S.

Great Security
My head is totally ringing afterwards. The light combine with the sound can really bother an attacker or animal close by. Even my dog didn’t like the noise. It was loud and bright flashes.
