Utilizing A Flashlight Stun Gun For Personal protection

I have been searching all 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 motor vehicle as it is, but I am wondering just how big this type of product will be to bring out for jogs or walks during the night with my dog?

I love that it works just like a typical flashlight, but that you also have the added advantage of having the capacity to drive away attackers with a jolt from the stun gun. It appears as though this will be an excellent match for me.
