You could improve by following the ideals you put forth. We bought luggage, the first time we went to use it, we were kit allowed the carry one on the plane due to their size.
We were told this would not be a problem. The 100 day return is only valid if you don’t use it? How would you know of you liked it, if it worked etc.. if you did t try it. So we are stuck with luggage we cannot use. We bought monos, better quality, better service and it fit.
