Hey
If you are having trouble with the cannon firing, call Mattel first before returning your N.S.E.C.T. Robotic Attack Insect, as it may need the black darts as opposed to the white ones, which they will ship free of charge. Yes, it's a bummer to have to wait for the new darts to fire the cannon. Also, we found the need for extra batteries fairly quickly. Overall though, it is very entertaining for both young ones and grown ups
