I waited until we took a couple of International trips before reviewing this luggage.  We LOVE IT!!  It is very maneuverable and its free-standing design allows you to stack smaller bags on the larger bags and successfully move large amounts of baggage easily yourself.  The design of the wheels and the corners of the bags allow them to stand up to rough handling.  The matte finish is very forgiving with the inevitable scuffs and scrapes that come from airport handling.  Our bags still look great after going around the world.  The TSA locks are effective and secure.  We used these for one "replenishment trip" to visit friends serving in a foreign assignment - the bags were completely packed to their expanded maximum.  We returned home with only one checked bag because we had the others compacted and nested within the largest bag.  All our own stuff was in the middle inside the smallest bag.  It was very convenient.  They would work just as well the other way if you took them on a "shopping trip" nested together, then expanded them for all your stuff to come home.  We love this luggage!
