Perfect red bag.
Filled my needs.  I did discarded the cheapo foam divider.  I loaded the bag with a specialized first-aid kit (wound-care supplies) for a two-week road trip.  Also, I liked what one reviewer wrote and cut a piece of cardboard box to add some rigidity to the main compartment.  As to size:  Its big enough to contain my supplies but small enough to pack nicely in my car.  I chose the red color to distinguish it from my other luggage.
