I want to confirm that it requires strength to throw, as another user pointed out. You can also see it as an exercise for your arms because it throws both in pulling and pushing. I know it is not recommended for use in the sea, but after using it with seawater, the cannons stopped going in and out, but they continue to throw. Because it throws two thick beams, the water runs out relatively quickly. I would have liked it if they threw alternately in bursts.

Good water gun. The only downside is that it requires a little force to shoot (at least for kids), which affects its accuracy a bit because it shakes right-left while shooting. Also, the shooting distance is not optimal, but it's fine for short distances.
