I love my TravelPro. It has survived 7 years. It's getting banged up (soft sided, black) a little bit. But one thing I love is it is easy to repair. The lining comes right out and you can tighten or replace screws for the handle and the wheels if need be. I have only had to repair mine once, but the handle was busted and I was able to easily repair it myself in a hotel room.
I am thinking of replacing it, with another TravelPro. It really has been through a lot of baggage handling systems, and EWR chewed it up a couple times. It came out the carousel looking like it had been dragged all the way across the airport, but I cleaned it up with a wet wipe, and it was good to go.
