I loved it when I first got it, but after a year of travelling with it, during which it was my carry-on for all but two flights when it was checked baggage, it has not held up at all.
Initially the wheels started getting stuck and it was a struggle to keep it rolling straight. That has occurred for 4 months now and several liberal applications of wd40 helped for a short period of time, but the problem continues to worsen.
In December the button that allows you to telescope the handle got stuck and the handle would no longer collapse or extend. With a lot of fiddling, it is usually possible to get it working again, but it's not guaranteed, and the button is firmly stuck.
I guess I will have to try out the warranty, which involves paying for shipping.
