I like the design of the spill-resistant rubber to keep food separate in the compartments, and the general capacity is great. However, the overall design seems inefficient. The total exterior dimensions make this box too large to place inside standard soft-pack lunchboxes. When I pack lunches in these for my kids, I cannot place this inside of their lunchbox carrier. They have to carry just the Bento to school, which gives me nowhere to place their napkin, utensils, drink, etc. I also have the kid size version of this, which is slightly smaller (and I can therefore wedge it into their lunchbox but just barely), however that version has a lot of wasted space too. With some design tweaks, the exterior dimensions could be shrunk to fit most standard carry-lunchboxes without losing too much interior food capacity.
Love how each section is spill proof and condensation doesn't build up and get into other sections. Took away one star because divider comes out very easily and already has been lost (kids under 5) and I've had less than two weeks. Because of this, dividers should be sold separately.
My two kids (6 and 3) use these for first grade and preschool. I love having the different sections including the optional divider so I can easily pack a balanced meal without depending on prepackaged stuff or wasting a million plastic bags. We just take it out of the backpack as soon as they get home and quickly wash it so it's ready for the next morning. So far so good!
Perfect use for me or my toddler! Large compartment is perfect for a toddler fork/spoon (with the sliding divider) and the main portion on the other side. I found washing with a bottle brush is easier than a sponge to get in all the groves.
