I have to say: I love the PBox and so does my 9 yr old dd. We have only used it for a couple of months now, but it has been the closest thing to a perfect lunchbox. It's true that the size of the compartments won't fit some kinds of foods (for me the main problem is rectangular foods like burritos or sub sandwiches; which will fit, but you need to cut them in half.) Overall though, I wind up packing more total food in the thing than I ever did in our old bento boxes. The outer case holds the drink in one pocket and the other pocket is pretty large and can fit good-sized snacks.
I love the slim little freezit thing, which is less cumbersome and heavy than anything I used before and keeps the lunch cold enough all day (it is still cold when she gets it home).
And I love not using plastic!
