It's a solid bag, but the wheels vibrate a little when I pull it at a fast walk.  It's my first Tumi, and I'm not sure I see what makes the Tumi better than everything else, but I've only had it on one trip.  There are a couple fewer usable small pockets on the outside than I am used to for easy access to plane tickets, water, etc.  The suit compartment in the top is not wide enough for my suit coat without crushing the shoulders - I am an average-sized man 5'10" 165lb, 42" coat.
