i just got mine last week and while i havent used it yet i do like it the material is satiny not a more durable matte like the other jjb bags.
i like that you can adjust the straps and tie it differently, though from what i've read and what i can tell with playing with it, if you do an adjustable type knot it would slip EASILY as the weight of a packed bag plus the satiny material would make it do so.
i like that it's reversible and it has one open pocket (back) on one side with wipes sized pockets on the front and then the reverse side has a zippered pocket. it's generously sized, so it would fit a book or magazine if running to the doctors...though remember it won't carry heavy stuff...i think the straps would just slip.
it's actually bigger than i expected, but i do like it.
