I ordered this to replace my 9 year old daughter's school bag. It was a bit more than I wanted to pay (after including postage), but the bag did not disappoint. The zips feel very sturdy and smooth. The bag is very big; big enough to fit my daughter's PE kit, books, homework folder, coat/raincoat and umberella in the side pouch. With all this, it does stick out a lot, but she doesn't have to carry anything in her hand. We keep asking if it is too heavy, but she says it fine! I think the broad, comfortable shoulder straps help.
