the quality of backpack is fine. Using experience 1 month. Thank you for item. Can't write the same about delivery. The delivery of CSE was more then awful. I spent a lot of time with communicate with that company. As result resolved take out product myself from item of that company. Don't recommend use that logistic company. Have never saw such bad service.(that is my experience, may be you will be more luck, rating of that company in internet ~1.5 from 5)
