Our recommendation
Buy the OmieBox if you send warm food to school and want hot and cold in one box. Buy the PlanetBox Rover if you want a durable steel box for dry grazing lunches and easy dishwasher cleaning. Both suit school, but they solve different problems: temperature against durability.
Temperature
The OmieBox carries a vacuum-insulated jar that keeps hot food warm for hours, with cold compartments beside it. The PlanetBox Rover does not insulate at all, so food arrives at the temperature it was packed at. For warm school lunches, there is no contest; for cold or room-temperature lunches, the Rover is fine.
Sealing
The OmieBox seals each compartment and the jar, so yogurt and dips stay where they belong. The Rover has no silicone seal, so liquids move between compartments if the box tips. If your child eats yogurt or dressing daily, the OmieBox wins; if lunch is dry foods, the Rover is fine.
Weight, cleaning, and longevity
The Rover is lighter at 1.2 lb against 1.7 lb, it is dishwasher safe while the OmieBox is hand wash only, and its steel body has nothing to wear out. The OmieBox needs more daily effort and its seals need care, though they are replaceable. Over years of use, the Rover asks less of you; over a single school day, the OmieBox does more for you.

Strengths and limitations
Omie OmieBox Bento Box with Leak-Proof Insulated Food Jar, Sunshine
Strengths
- The removable 18/8 stainless steel vacuum jar keeps hot food warm for hours, so pasta and soup can go to school.
- Two temperature zones let warm food sit beside cold fruit and veg without either side suffering.
- Three compartments plus the jar cover a full meal in one box, with no bag of extra containers.
- Seals and dividers are replaceable, and the box comes apart for a thorough clean.
Limitations
- At 1.7 lb empty, it is the heaviest kids box here, and small children feel the weight in a backpack.
- Hand wash only, so daily cleaning takes more effort than a dishwasher-safe box.
- The latch can be hard for small hands to close, and the jar seal needs care to stay fresh.
- Warm retention depends on preheating the jar, so a cold jar and cold food will not warm up on their own.
PlanetBox Rover Classic Stainless Steel Bento Lunch Box, 5 Compartments
Strengths
- Solid stainless steel construction stands up to daily drops and years of use.
- Five compartments, four main plus a treat spot, suit grazers and picky eaters well.
- Dishwasher safe, so cleaning is a simple rack load rather than a hand-wash routine.
- Works with PlanetBox dippers, pods, and bags, so the box can grow with your packing habits.
Limitations
- Not leak-proof between compartments, since there is no silicone seal in the lid.
- No dippers are included with the basic Rover, so wet foods need separate containers.
- Cannot go in the microwave, so hot food must be packed in something else.
- Steel shows dents and fingerprints, and the box feels cold to hold on winter mornings.

Questions, answered
Which is better for a 5-year-old?
It depends on the child. The Rover is lighter and easier to clean, but its latch-free steel lid needs a bag that keeps it flat. The OmieBox is heavier and harder to close for small hands, but it carries warm food. For most 5-year-olds eating cold lunch, the Rover or a Bentgo Kids box is the easier choice.
Can either box go in the microwave?
No. The Rover is steel and must never go in a microwave, and the OmieBox is not made for microwave reheating either. For microwave lunches, choose the monbento MB Original or the Bentgo Easyboxes instead.
Which lasts longer?
The Rover, since a single steel box has no seals, latches, or jar to wear out. The OmieBox can also last for years, but only with seal care and replacement, which is a real ongoing cost in effort if not in money.
