First it feels like you're on fire, then you lose all muscle control, and start thrashing around, you pee your pants, then you fade in and out of consciousness, when it's over, you feel like you've been hit by a truck!!
Been there, sparked that! Everyone handled it differently. Some wet them selves, some scream. The common denominator is that their muscles contract and they fall down. Not everyone can be subdued with a Taser, because it works by severely contracting your muscles. Severely obese people do not feel it as much. I've seem a 400 pound man get two good hits from two different Tasers at the same time. He stood there and said "is that all you got!" The things that make it work best is the spread between the two darts. The muscle mass of the suspect. What does it feel like, one extremely massive cramp of almost all of the muscles in your body. A burning sensation where the probes are. Keep in mind, the first short or two is with the probes sticking into you. If that doesn't work Taser instructs you to drop the launcher, and drive the probes on the gun right into the persons private area and pull the trigger for a 5 second shot, redo as needed until the person complied. My son thought that there was enough rubber on the bottom of his tennis shoe to stop the pain. He felt a little of his 5 second ride. But after it was over the sole of his shoe got extremely hot!
I don't know, quite frankly, don't want to know. But, you can ask any police officer or the authorities. Anyone who carries it will know. In order for a police officer to carry one, they have to know what it feels like incase they are tasered. Same goes for pepper spray.
