I have had this bag for over two years ago based on a friend's recommendation to buy this bag.  I have taken this bag to Central America and to Africa as well as used this bag up and down the eastern part of the US.  I can hold everything you need for a week if traveling to warm regions for one person or three days for two people in the dead of winter.  The carrying options between the straps and the wheels are all rugged.  The only damage to this has been to one of the zipper pulls that got eaten by an airport baggage belt.  Replaced it with a piece of cord and it was ready to roll on.  Not the lightest bag in the world but worth its weight in durability.  It is easy to clean out and doesn't retain odors.
