Usage

How It's Used

When initially removed from the packaging, the Saturator requires 4 AA batteries for operation (batteries not included). The batteries are inserted through the base of the water gun. After battery insertion, the Saturator needs to be filled with water before it can be used. This process is described in the image below.

User Studies

Overall, the Saturator AK-47 Water Gun performs at the average standard for toy water guns. While the water container or clip stays in place, the gun needs to be refilled very often during play. Another negative aspect of this product is the range of shooting. Although it is advertised as a gun that can shoot over 25 feet, the stream of water barely makes it a distance of 15 feet.

In comparison to the Banzai Color Stream Blaster Water Gun, the Saturator is lighter and easier to maneuver.....
