I had been looking for a new carry-on bag for air travel. Prior bags have been too small, or too soft, or larger than would fit in some of the bins, or....  This bag is the right size, being small enough to fit the overhead bins, but large enough to carry enough stuff to last a few days.  It was easy to maneuver with the wheels (so I didn't have to carry it on my shoulder like my old duffel), and was just a joy to have.  Looking at the bigger version to replace my big bag.
