Lightweight and fluid, a semi automatic so you have to shoot the gray part to load the gun before shooting each ball. The viewfinder can sometimes be used if you play to target objects. Rechargeable easily by pressing the orange button that go out the location to put the balls. No batteries required, this is an advantage and it is not noisy. Small flat, hard balls with their end can hurt when they are children playing, and the dark blue color makes it difficult to find them on the ground after. The Velcro balls oranges available in stores, collide and it's better to find them because fluorescent orange color. I recommend.
