My son loves this backpack. His last one was not sturdy and the wheel bracket had disconnected itself from the backpack and would not stand up on it's own. So I decided to purchase him this backpack... I was surprised by all the compartments inside the backpack. It was more than I expected and the construction of the backpack is very sturdy... it stands on its own and holds alot. I would recommend this to anyone who needs a stable backpack with wheels. My son is only 10 yrs old and brings home tons of books and I dont want him carrying all the weight on his shoulders and back daily so this was a great help for him and a great buy for me.
