Review title: Sad on Christmas
Product review: My son is a total "Batman Begins" fan. Everything on his Xmas list was "Batman" which inlcuded this car. It was very disappointing for him to open this car and find out that the additional battery which is packed by "Tyco" was not included. The 9V battery is easy to get and also packaged so that you know you will need it - but otherwise a major waste of time. The search for this other battery is something I would not recommend for another parent to endure. Best advise - DON'T GET IT!
