The bookbag was of great quality. It was very sturdy. I bought this for my 3rd grader b/c she had tons of books to transport to and from school. But it is so well made, that it makes it a lot heavier than the average rolling bookbag. My daugher could not even lift the bookbag once it was filled with all of her books. However, she loved it and we were able to make arrangements to leave some books at school. And as many of the other reviews stated, one of light up wheels stopped working after a couple of weeks.
