Bought the CalPak Grand Stand Rolling Backpack for the 2012-13 school year (2nd grade girl). It lasted all year. The handle was a little temperamental on that one, and one of the handle "bars" came out on the last day of school. My daughter was REALLY rough on it though - dragging it up and down the bus steps, slamming the handle up and down - you know how impatient kids are when things aren't working the way they want them! But we made it through the entire school year with that backpack. I bought a new one again this year for the 2013-14 school year. She's now 9 and in the 3rd grade. She's not so rough with it this year. The handle isn't at all sticky like the first one was, so she's not slamming on the handle like last year. We've been using it 2 months now and I'm very pleased with it. I'll probably buy another one for the 4th grade.
