30 minutos - 2 horas
The problem was the battery, i had to take the chance of trying myself it was only 19.95 compared to $200+ of a new ipod...
It was very difficult to open the ipod but after that was a walk in the park. Although the ipod is not the same, i can live with it just a few scratches...
My advice would be to buy a more complete tool kit or maybe the putty knife and two extra plastic tools beacuse their not hard enough.
