Actually, I was quite happy with the bag, the notebook fits very well in and is certainly there. But before about 2 months broke down the zipper. Unfortunately I have not yet found a way to contact, if necessary, to find the seller a solution. I have only once used the bag a week, since I need it only for school. Now the zipper is obviously defective exactly on the main compartment, so you can no longer use the bag also for transporting the notebook's because it can fall out now. Therefore, currently only 1 star.
I would be delighted if the seller would contact me and we could together find a solution, because I was very satisfied with the rest (shipping, payment processing, etc.) else!
