Feature: 1. The design of our hopper is below instead of above, to avoid the dangerous behavior that the water of the gel ball will flow into the gun and cause power failure. 2. We have distributed a total of 10,000 gel balls, which are very large enough for children to use, so you don?t have to worry about being consumed soon and you need to repurchase them. 3. The gel ball blaster is equipped with a safety switch that can be turned off when not in use. It also has a silencer to reduce surrounding noise and can be detached for use. 4. When the battery is fully charged, the water gel gun can play for 4-5 hours, which is enough for children to enjoy outdoor activities.?Warning? Must wear goggles(included) when shooting and do not aim at eyes or face! The recommended for ages 12 and above.What should you do if get stuck or cannot shoot water ball? 1. Remove the magazine for a test first. If the water ball cannot be ejected, re-soak all the water ball in hot water for 2-3 hours to achieve the best effect of 7-8mm. The soaking water must be higher than the water ball. 2. After soaking, reload the water ball and then do the pumping test. If the water ball can eject out normally, it proves that the gun is no problem. (Reference video: https://youtu.be/1lGIG5fRH-0) 3.
