I've had this bag for about 6 years, and it's still in great condition. Still no tears or wearing on the handles, strap, or anywhere else. I carry it daily. It fit all my papers and folders as a student as well as my Toshiba Qosmio X75, which is by no means a small laptop. Now as a professional designer, it meets all my needs with more than enough space. I can't imagine having a different bag.
I bought a Lenovo Legion Y540-17IRH recently, and it fits in the bag as well. Giving the bag away with my Toshiba to a family member in need of a laptop and about to buy me another. Highly recommended.
Side note: It's a thick bag, but if space is a concern then this is your bag.
