Has a defective battery - Can charge for hours and immediately shuts down after a minute - Very upset because my son (a little autistic boy ) got it over Christmas but thought maybe he did something wrong (he didn't, it was NEVER used by us because he couldn't connect) and thinking he did something wrong he did never told us about it. It felt like we overpaid for FIRST DAY when I assumed it would work - needless to say the feeling didn't improve when we didn't have a single minute to use this thing!
