I'm sure it is. I've did the video that caught it 4 times before it went bye bye.
Whole shit happened in 1 minute 30 seconds. Or close to that.
It may have saved some lives as those are sort of uncontrollable. Hard to acquire a new target after two pops and you don't know where the thing is pointed. Especially for a skinny fuck this this POS. He probably needs treatment for his bruised shoulder.
They are useless in my opinion.
