The school Trolley I had for my son so he ordered the heavy bag (High School) do not always have to wear back encouragingly. I was thrilled as has plenty of storage space this school trolley and can be drawn in spite of the weight of the whole school supplies. Unfortunately, after a short time the camp broken so I could replace it. But to my displeasure, it has unfortunately been repeated several times. The extender bar is also very unstable after a short time and if you're unlucky this can be no longer completely retract. My conclusion about this product, for use as a school Trolley this is not suitable because it (transport school supplies) the normal stress does not stand up.
