I bought this taser for personal protection on my long evening walks. Every time a stray dog tries to attack me I just press the button for one second and it scares the dog away, I don't even have to come into contact with the dog! It's very small yet very intimidating, it makes a loud electrical noise that scares just about anything and everyone. one full charge lasts about a week with normal use, I use the flashlight more than the taser.
