I must this bag for some time now call my own and have to say I am convinced. My laptop is a little too big for the laptop compartment, but I did not previously clear, so I can as well say nothing. But is not a problem, because I can still use the tray for other documents. It is processed really decent and has just the advantage that is also easy to clean by the processed materials. Eben just enjoy it wipe with a slightly damp cloth and all is well.
The only drawback is the shoulder strap. This can not be set far enough for my personal use. So I can only wear the belt on the shoulder on which the bag hangs. Otherwise, everything was perfect.
