Making use of A Flashlight Stun Gun For Personal protection

I have been investigating all of the different alternatives for self-defense products and I am interested in the flashlight stun gun. I like to keep a torch and some other light tools within my vehicle as it is, but I am wondering just how big this sort of device will be to bring out for runs or walks at nighttime with my dog?

I like that it operates just like a regular flashlight, but that you also have the added advantage of having the capacity to keep away assailants with a jolt from the stun gun. It appears as though this will be a perfect fit for me.
