Am disappointed! A lot!

I bought the backpack beginning of March 2012.. He looked in the pictures stable and robust, visually he also said to me, and the cheap price was then the last argument for buying.
When he arrived home, he met at first my expectations. He was also well made. Ok it might be a bit small, next to a small A4 writing case, lunchbox and a 1.5L PET bottle does not fit a lot in.
But then what has really disappointed me, that was after about 1 week of the big bag zipper broke. And a week later, the seam of the wrist strap began to dissolve. Meanwhile, one side of the wrist strap from half. Let's see how long it lasts nor :-(

Definitely not by me buy recommendation!
