Taser is a brand that sells electroshock weapons. Cops in many countries including the United States have started using it because it is the least lethal weapon among all other weapons to subdue a target. Taser devices can fire the electric probes at distances up to 15 feet, or they can be used at closer proximities to deliver the electric shock. A taser gun is a great tool for self-defense, especially for women. Taser usually is not lethal that is what makes it a great choice for self-defense. However, with every self-defense weapon, you need training. The problem is that most people are not trained to use this tool under pressure and extreme stress. But if you have the proper training to use it when under pressure, this is the best tool that can save you if you ever were to get attacked.
