I needed a clear bag for work.  This looked satisfactory.  I bought it in august of 2012, and despite heavy use (I tend to overstuff my bags, including 1-2 hardcover books), it's only JUST developed a hole in the vinyl (and that's courtesy of my cat making biscuits with his sharp claws).

The pocket, where I dump all of my loose change (amongst other items) has also held up well.

None of the seams has split anywhere on the bag.
