I LOVED the look of this bag.  I am a home educating mom and I go to library sales and curriculum fairs.  I wanted something stylish, but functional to put books into to make my life easier.  This is not it and is being returned the day after purchasing it.  The description states there is a locking handle and while it should lock and has a design to lock it in fact collapses with the slightest pressure.  I saw reviews that stated this, but they had stated that they couldn't return theirs since it wasn't in the description.  So I went and read the description and it indeed stated "locking handle" so I assumed the problem had been fixed.  Not so much.  Also it appears that it is a squared off bottom, but there were only smaller books that I could lay flat and if the weight isn't perfectly distributed it tips over.  That was so much fun, yeah not so much.  I did like the front mesh pocket and the one on the side.  I had my keys, cellphone, and wallet up front, water bottle on the side.  For serious book buyers that is convenient.  The other options are all the crate looking styles and I wanted something to hold items like that.  I want my hands free to browse.  So if they could square off that bottom better, lock those handles better and fix the balancing issue this would be a great bag, but don't let the pretty package fool... this is not the bag you have been searching for.  I'm disappointed.  Absolutely first return to Amazon after YEARS of continuous shopping.  Typically I am the type to eat a bad purchase if it was in my error, but not with this one.
