I feel very safe on my walks now. The alarm is loud and the device fits in the palm of my hand.

I purchased 3, one or my daughter,my granddaughter and myself. I am very pleased they make you feel safe.

Bought this for night fishing. It's great because I can turn it off and on just by waving my hand. Don't have the bugs constantly in my face. I've since bought a couple more and recommended it to friends.
