I was a little skeptical about the durability of this luggage set after I received it.  I travel internationally frequently and have been pleasantly relieved of my original skepticism.  The luggage structure stands up to the rigors of airport baggage handling well.  The spinner configuration is a great benefit in herding several bags at once through the airport, and minimizes trips to the car for unloading at home.  The finish is the only item on this luggage set that is showing wear after about 4 round trips overseas.  I wish the carry on had an external document net or folder
