This thing has less than 10 minutes of total use since it was opened on Christmas. There is absolutely positively nothing wrong with it and it has no damage. It's just too big for my daughter to handle right now. It is fully motorized so it does not need to be primed in order to fire. It shoots the little yellow Nerf balls, not the darts. It comes with 100 of the yellow balls and the instructions. I will also throw in another set of batteries for it. This thing retails for $78 brand new and is basically brand-new. Cash only no trades! Please no low-ball offers. Any other questions, feel free to ask me.
