We have only used this luggage on one trip /4 flights.  So far we really like it.  We bought both the 25 and 21 inch.  Both hold a lot of stuff and if it is overstuffed can be expanded.  The compartments hold a lot and use straps on one side to hold clothing in place and a zippered compartment on the other side for loose items.  It rolls really easily, is surprisingly light weight .  The 21 fits into an overhead compartment.  The 25 is for checked in baggage and help up to the handlers loading.  except for some scratches it seems fine.  Also this has the new TSA lock so you can lock your luggage securely.  I have some more trips coming up and will follow up with more once these have more miles on them.  i gave it 5 stars because it did everything we wanted .  Hope this review is helpful

update; aside from a few scratches from the rough handling at the airports, the luggage still looks and works great.
