First of all the colors. The thing lights up almost in the dark, especially the more saturated orange. I (and my kids) like the very good and the road someone falls with this backpack quite sure on. The material seems quite durable and properly processed, both zippers are equipped with counter-rotating zippers. The side mesh pockets are well used (smaller bottles fit well in), both main compartments are internally divided again with the larger lined a (formulated benevolently) laptop compartment features. But the feeding then provides for the withdrawal of the fifth star. Feeding the shoulder strap is still ok, which is expected to the back wall but much thicker (or even ergonomically designed) so that the backpack rather than more for occasional short-distance (eg in training) and lower loads is designed for longer hikes and lasting wear. In contrast to the illustration just this rear wall is incidentally orange and not, as shown, black.
