"This bag is adorable and my daughter loved the pockets but it is very poorly constructed in terms of balance. It does not stand up either empty or filled and needs to be propped up against the wall to stand up. The wheels are also made of cheap plastic so dragging it through an airport is VERY noisy and almost embarrassing. For $50 you would think they could use better quality rubber wheels to make it roll more smoothly. We were very disappointed with this product and upset we spent so much $."
