I bought this for my friends daughter and my daughter loved it so much, she wants one too! It is a little expensive, but is a PERFECT backpack! It has a lot of room and a lot of great pockets.
Both my sons are using their rolling Critter backpacks for their second year now. Overall, I am happy with how they are holding up. They are very sturdy and well made. This makes them quite heavy though and my younger son complains about the weight as he has to carry it up the stairs at school every day. Another criticism I have, that they are very hard to clean. LL Bean recommends spot cleaning only, so once they get dirty, it's almost impossible to get them clean again. I've learned to stick with the darker colors. Also, the handle could be longer. It doesn't work very well for any child taller than 50", as they keep kicking the backpack when pulling it.
