I've just returned from this rolling backpack's maiden voyage and it did everything I wanted it to do and more!  It has an incredible amount of room and wonderful solid, as well as mesh zippered, inner pockets to organize everything.  It rolls easily and although I had it jammed full it never tipped forward, even though it looks like it could.  I kept my zip-lock bag full of liquid items in the frontmost pocket, making it easy to take it out and place it in the airline search trays and then replace once we cleared security.

The only problem I had was that the handle sometimes didn't collapse all the way down without a fight; however, I discovered applying pressure in a certain direction while I pressed the button on the handle solved that problem.

Yup, I would buy it again.
