I've been using this bag 5 days a week back and forth to work for the last 2 years.  I really like the color, the layout, 2 end compartments, the heavy duty nylon and the straps.  Unfortunately it is poorly made.  Zipper tabs just break off (probably zinc alloy metal, not steel), stitching becomes frayed and undone and the bottom outside plastic coating has flaked away.  The side pouch is great but the liner tore into the main compartment - that's probably my fault for carrying a lot of heavy things there.  Having said that, for this price it might be worth replacing every few years.
