The LE model X26 delivers 50,000 volts for approx. 5 second bursts.
Every muscle in your body flexes/tenses up so you can not move or resist which gives officers a opportunity to control the suspect by handcuffing them.
I rode the lighting for 5 seconds and it was the worst feeling in my life but once the electricty was shut off your body will completly colapse and your muscles will return to their normal activity.
This tool for LE is a great one because it gives up another option to use against a combative subject when other means have failed.
Just my 2 cents worth for you all.
