I have bought two of these for my pre schooler and my kindergartener for the school year (the monster and the bug one).  While very cute, I could tell right away that they weren't very sturdy to hold up to hard usage.  Sure enough, after less than a week, my kindergartener's backpack's front zipper is broken.  I have to replace that now, and I'm sure it's just a matter of time before the pre schooler's backpack dies too.  So, save yourself the money.  It would be nice if there were cuter options in sturdier backpacks, but having one last less than a week is just unacceptable.
