This is a Paint granade guys not AS. The bang is pretty impressive but you have to make sure that the weather is pretty warm when you deploy these or else they they don't work too well. I've only tried this onec and it was pretty disapointing. the delay was more like 10seconds and not the 4seconds that it claims. The radius was...well nn exsistent. I contacted the manufacturer and he says that if its cold out it won't work. It was about 25 degrees out, and it had been in my vest pocket for a bout two hours and still pretty lousy. this is just my experience.
