Travelpro Bold. 25" expandable. Not a very expensive pice, but a wheel came off, luckily as full time nomads, husband McGyerverd it, and it got us thru til we got home. Contacted Travelpro, they had me take a photo and I had registered it when I bought it ( one year prior). 24 hours later, I got an email asking where I wanted the new suitcase to be delivered.

So, I have no experience with repairs, just replacement. And for the "low-end" piece.
