Utilizing A Flashlight Stun Gun For Personal protection

I have been investigating every one of the different options for self-defense products and I am considering the flashlight stun gun. I love to keep a torch and some other light tools inside my vehicle as it is, but I am curious about just how big this kind of device will be to bring out for jogs or walks during the night along with my dog?

I really like that it functions similar to a common flashlight, but that you also have the added advantage of being able to drive away attackers with a jolt from the stun gun. It appears as though this will be a great fit for me.
