I'm a volunteer tutor for homeless children and I must say, after purchasing this backpack on wheels for one of my students I really liked it and she just loved it!  She's in third grade and takes it to school everyday, has it nice and organized because of so much room to do so and really loves the fact that her back no longer hurts because she can roll her books and materials around instead of carrying them.  She loved the color and design, as I did as well.  They have quite a few "cool" colors and designs that I know kids really appreciate.  I'll definitely continue to buy these in the future for other children I work with.
