"I wish I would have never gotten this for my son for his birthday. The charge for double a batteries is so horrible you have to change out weekly. After a month and a half I just couldn't afford to keep buying batteries. So he hasn't been able to play with it since. I just got enough to money to invest in the recharable battery. Received it today. Still can't play with it. It did not come with a power cord. Now I have to dish out another $30.00. If you plan are using robot daily then invest in battery. I just don't understand why they just don't charge the difference and put the recharageable battle in this package. Horrible expierence."
