The instructions don't say to pull the black cap off before throwing so make sure that you do, I did not pull the black cap off. I throw hard and nailed a random in the shoulder just to have it bounce off I was expecting the nade to bust but it did not. so I had to retrieve the nade in a hailstorm of paintballs (playing Iron Man) and heave it against a wall to get it to bust paint on my target. So user error made me unable to see proper use of the nade. ON the ++ side its cheap as can be, I only got it cuz I had a few bucks leftover in my budget, it was still worth it people were scared of the NADE and ive always wanted to yell GRENADA!!
