Although a little small for University, (with a textbook, notebooks, and lunch, it is a little tight) this bag is very comfortable and durable. I have only been using it for 2 weeks now, but I love all the compartments and quality of the backpack. The straps and backside of the bag make carrying a heavy weight quite comfortable.
For its size, it does hold lots of things, but for my needs, I was hoping it was a little bigger.
The only improvement I would suggest is to add side pockets to hold a water bottle as it does not currently have this feature.
