Who pays little, little gets ...

I bought the item for my son. This is in the 4th grade. He wanted to wear no more satchels and so we opted for this trolley. Now the product:
The processing seems to be sufficient, but I do not think that this survives the school year at the extreme stress in schools. The rod to move out makes a unstable impression and also covers the roles rattled at the beginning. Once the cover has also been so uptight that I with the tool roll to roll again brought them only.
The processing I give a 3-4 (school note principle)
Appearance is a matter of taste
Handiness I have to give a smooth 4! The trolley stays when it is loaded with books, not just standing. He always tilts forward! Thus, the satchel is always dirty. This is due to lack of solid ground.

Conclusion: For children, this is only limited use as a schoolbag spare!
Would I buy this again: No!
