Well we are having a little difficulty with the gun. It's works great for a few minutes and then it stops. Seems as though the battery is not keeping its charge. We have to keep charging the battery constantly. My son doesn't want to part with the gun and we are deciding whether or not to return it. Maybe it would be a possibility for you to send him a new battery pack as not to have to send back the gun itself. He is very happy with the gun as long as its working. But he has to keep stopping to recharge. Thanks! Maybe you can help me out with this. :)
