I still have the used one for sale. Please contact me with a PM if you're interested.
I've been telling people one by one why I'm selling them, and rather than keep that up, i'll just post it here. Despite the great things others have said about them, my luck has not been so good. On the first trip we took these on, one lost its wheels and axle when we had to check it at heathrow. The company sent us replacement parts, free, no problem, after we got home. On the second trip, one case's handle could not handle the trial of going through a carryon xray machine. It got a little bump, and that was that, it would not lock up or down, it just flopped around. It came off. This time the company replaced the whole case. That's how I got the new one. They never left the house again; I won't get fooled again.
I'm not sure which one had the axle problem, the used one I still have or the used one that got returned. I'm not sure it matters. The axle is as good as the original one. The damage was always caused by handlers and machines, not me.
Despite my bad luck with these, others have had great luck and love them. I'm selling this for about half the original price, I'll take $175 for it.
