I chose the Holla At Me personal alarm. I have to confess that I have not tested it because I am just *that* scared at how loud it is (but that's a good thing)!
There are a whole bunch of tools and products that can help you feel safe-- even when you think you're in your own "safe" neighborhood. They're girl-themed (read:pink and small!), and some are cleverly disguised as lip gloss or a mini-purse or cell phone.
You can check everything out online OR you can host a girl's night party and rep Robin will come show you how everything works!
*I was given a product at no cost as the result of winning a contest, but this post is my own opinion!
