15+ years of use and still looks relatively new

Got this in college when I was a student athlete traveling weekly 6 month of the year, after college it gets used monthly or bimonthly for business or pleasure.  Its never let me down.  Buy once and cry once is my philosophy when it comes to things you will use often.
I also have a briefcase/laptop bag, an overnight bag and a wheeled duffel(only the duffel is new and thats 3 years old now) never had an issue with Tumi
