I wasn't too sure about this when I started using it, but I realized over time I was just having "new bag" issues, i.e., learning where to put/find things as compared to the bag it replaced.
I've decided I don't love the flap-over buckle design as much as the soft briefcase style I was using prior. If you pick this bag up without the flap buckled, you're almost certain to lose anything tucked in the front flap. I think a zipper or other closure on that front space would be useful. I'm also mixed on whether I like the single, big open space in the bag versus a design with compartments, but I essentially solved this by using a series of drawstring bags to organize items within the single large space.
The mesh outer pockets are perfect for holding a water bottle, or small items that you need ready access to. The strap, handles, and zippers are all of decent quality; I'm pretty hard on bags, and this one has help up quite well for the past few months.
Other than some design modifications that would make more sense for me personally, this is a decent bag and worth the price.
