One of the wheels was clearly not aligned properly and even wobbled up/down when it rolled. If both wheels are not straight, they wear out prematurely (like a bad tire alignment on a car). This was very obvious - does Travelpro have any quality control? The box didn't have a scratch on it, so this was not caused by shipping damage. Also, the pull-up handle didn't feel or look very substantial and had a lot of play in it. If not for the Travelpro name on the bag, I would have guessed this was just another cheap offshore product. This was my first Travelpro bag - it is being returned and I'm done with Travelpro.
