I had now torn the backpack no 7 months in use, already are the most good. And I was not very often so the move, only 3-4 times per month. Interior layout is also not very stable, my 60D control exposure only unegnügend. I have transported so that the camera and 3 lenses, so not too much weight. Since it was saved at the wrong end ...
All in all, I've learned my lesson, rather invest 30 more and buy much better bags or backpacks.
