Long story short: Had TravelPro large suitcase. Used it twice and never even checked it. Second time, it tipped over in the hotel room. The pull out handle was bent so bad it wouldn't retract, making the case (which was in otherwise pristine condition) unusable.
E-mailed the company, but they made me take it into their "Authorized Repair Center," 45 minutes from where I live (one way), before they would even comment on whether their "lifetime warranty" would cover it.
After several e-mails and calls, and 3 hours and counting of my life, I am told that they won't cover the costs of repair, which are about $40.
Any suitcase that tips over once and becomes completely useless is, in fact, defective. They should be built to take a minimal amount of normal use, and I have several pieces of less luggage that have endured much worse.
But, TravelPro feels otherwise, and seems to believe that its business model is better served by saving $40 (or, I imagine it would have been even less for them)than keeping a customer.
I got the run-around for nothing, when any other company would have been bending over backwards to make things right.
