My local park uses these things. They are awesome. I have a membership and there's a $20 coupon, so these are the best $45 a case paintballs I know of. REALLY GOOD ACCURACY! They are hard to find, so buy 1-3 cases each time you see them. . . . . . . . . . .. . .
They are hard to see in the woods when it's dark, but the paint shows up really well.
