So far I love it.  It appears to be of good workmanship and it holds all of my necessary items.  If you are a stuffer, you will not be happy with this bag.  It will not hold a bottle of water comfortably but all of your IDs, passports, tissues, keys, lipstick, mirror, credit cards, and my Kindle--the essentials, it will hold comfortably.  I like the locking zippers.  This makes it a little more difficult to pick things out of the bag.  Unless someone is carrying bolt cutters, it is unlikely that they will be able to grab this bag.  One of the outside zippers do not lock.  This might be a part of the product design.  The pocket is large enough to hold tickets and itineraries.  So far so good.
