Great backpack, quality materials. Sturdy wheels and well balanced, does not tip. Telescopic handle easy to pull and retract. Better sized (larger) than most rollaway backpacks. Zippers are smooth and don't catch. Can fit all of my kid's books, planner/keeper, and lunchbox. Nice vivid colors, make it easy to spot in a pile of schoolbags. Plenty of pockets for small items (pencil case, wallet, cellphone, etc.). Wish it also had a side handle--this big bag gets pretty heavy when full--difficult to lift and load in the car with just the one handle at the top. Otherwise, very good product. Priced well too.
