TravelPro is junk!
My bag, my wife's bag, and several people I've talked to have had the same problems with these bags. The handles break off, the zippers rip out, and the extendable handle breaks. They have a warranty, so it gets repaired for free, but it is a pain in the keister to have it repaired. Carrying all my clothes in a garbage sack while it is repaired is not professional. At least the heavy duty black garbage bags meet company guidelines: all black, no colored striping.
Edit: I do like the design of the bag. It is very functional, rolls nice, and looks good. I have the crew3. They may have improved the crew4 and addressed previous weak points. For the money, it not a bad piece of luggage. You will fork over much more coin for the purdy neat and other heavy duty bags.
