I was looking for a medium sized pack to carry stuff to and from my office.  I first spotted this pack at the bookstore of my son's university. I ordered it from  amazon to get a better price. All of the zippers open smoothly with no binding.  I live in a relatively dry climate so I've folded the rain flaps over and out of the way.  The pack has two main compartments and three smaller ones.  It has a mesh pocket for a waterbottle on the side.  An additional side pocket or two would have been nice but not a deal breaker. Shoulder straps fit ok. For the most part I use the grab handle on top or sling it over one shoulder as I walk from the parking lot to the building. Carries my lunch, laptop, notebook, small flashlight, G17 and a folder discreetly and comfortably. I would probably give it a 4.5 total.
