Query: Fun at a great price

These are fun to use and works like a more expensive gun without the high price. Caution to people who have not used these guns before though: the balls can hurt and also be very careful to pull the lever on top otherwise all the CO2 will run out for the next time you want to play, or you can buy a refillable cartridge. We have all had a fun time playing and the accessories that come with this gun are essential to have to be safe.
