I have had this bag for about a week now.  I use it for carrying text books, notebooks, etc.  It is generously sized and feels extremely durable.  There is one slim pocket on each side that I have not found a purpose for yet.  I would recommend making them larger or removing them.  There is a zipper that closes the main compartment which you might not use depending on your application.  This zipper has smaller pulls and there is no cord on them.  The zipper does not slide that well due to the lip of fabric on each side of the zipper.  The shoulder strap is not padded either.  I think that it will last a very long time the way I am using it.  I have other maxpedition products and they are very rugged and reliable.  I hope this review is useful in making your purchase decision.
