I ordered it on line I received it quickly. It’s very easy to use and I have it clipped to the ring on my purse strap, and looks stylish especially in the silver. It can easily be removed and carried in your pocket, backpack, wherever you want. I’ve shown it to a couple of friends and they had positive reactions. One friend said if she had one, she would not have felt so uneasy in a particular situation she recently found herself in.
I gave it 4 stars because I haven’t used it yet!
