Query: happy with purchase

I bought this for my son and in the beginning I was very dissapointed. After a few hours of watching it the batteries died and my son would get so upset, my daughter has video now and she has the same batteries in it from christmas and the batteries have not died yet So I was a little upset. I read one of the other reviews and someone said to invest in rechargeble batteries because it eats up the batteries so I did that and now we are all happy.
