I bought two (one in blue and one in purple) of these for my 8 and 10 year olds.  We took them to South America and they served us well!  There was plenty of room and all the pockets were useful.  Most importantly, the kids could roll them themselves without difficulty.  I was concerned that they would not hold up well as checked luggage, but they did great.  I was considering getting heavier-duty suitcases with 360 degree wheels, but decided in the end that it was just too expensive. I think I made a good choice.
