I love the size and shape of the bag and the design is totally perfect.  It glides down the airplane aisles with zest.  HOWEVER, I have used it on 9 trips during the past 3 months and now the zippers are broken.  The design is elegant, but the materials that it is made from are totally of the poorest quality.  When it finally falls apart (and that will be very soon), I am going to buy the identical-looking bag from Brookstone--at least if that falls apart I will know where to return it!
