First impression: good size & quality. many compartments to organize your stuff for easy finding. Well padded backs, shoulder straps and carry handle. There is a strap to slip onto luggage handles too. Ear phone hole and USB cable for charging etc. Con: front compartment has a single zip puller which is very inconvenient to quickly get to your stuff. Thank god there're double zip pullers for the back compartment, otherwise it's a goner. Also, at least on side pocket should have a zip or velcro too.
