Things I liked: Highly reactive and satisfying, great for developing anew shooters point of aim and concentration.
Things I would have changed: More disks per box, we eat thru these things like mad. The shards are a bit tough on bare feet!!!
What others should know: If you are having trouble getting someone who objects to firearms to try shooting... put a couple of these out in the yard!!! I got my pacifist wife to give it "a shot", she's hooked!!
