All of the damage to any of my luggage has been caused by airport equipment and/or loading personnel. The airline refused to be responsible.
Oh, I did have a hardside Delsey once upon a time that I also really liked but one day, it's shell cracked, a huge angled crack right in the middle of one side. I later read that it was a problem with that kind of shepl material. That's when I switched to the lightweight but highend Samsonites (on sale) and have never looked back.
I am not convinced that I'd be any happier with a Tumi or Riley and Briggs or some such. If one of those bags became damaged I'd be quite unhappy and then have to go through all the rigmarole of getting it fixed under warranty. Heck the Samsonites have similar warranties for 5-10 years, though for some reason I doubt the reliance on same.
Further, when my eyes became too bad to recognize my luggage coming off of the belt, I plastered it with neon pink stick-on shapes. Can't imagine that I'd be so inclined with an ever so much more expensive bag.
