This is an AMAZING carry on bag.  It is lighter than any of our others, even lighter than our hard-sided luggage.  The handle is easy to snap up and down and the wheels turn every direction smoothly.  There are an ample number of pockets outside to keep all of the smaller items.  The interior has great straps and dividers to make packing easier and organizing a breeze.  The zippers are large, but not too big and move smoothly, but stay in place well.  It fits easily in the overhead compartment when NOT expanded, when it was expanded they asked me to gate check it, but either way, it's a great bag!
