Good backpack for schoolchildren

I bought a backpack for my son, because he now in school is making more and more trips. But the backpack is well suited. The color is beautiful, the perfect size (son is about 1:35 in size) and the backpack has many pockets for odds and ends. The two mesh pockets are pretty deep and so far that a thicker bottle fits in and does not fall out again.

Now the things that are not so great: The zippers work filigree total. For a backpack I would have liked something significantly more robust. Let's see how long the join. And the fabric is also quite thin. Sure, this will the backpack easier, but I'm still worried about how long it is going well. He also has no waist belt, as stated in some reviews. At the lid plastic rings are attached, in which one can move a rubber cord. There you can quickly something lashing (jacket, cap, ...). I would have liked that this cord would have been at it. Even with cheap backpacks from the China Shop are already threaded.

In sum: A pretty nice rucksack with nice details and a small shortcoming in the robustness and Equipment
