The R3 Score is a weighted average of 10 criteria specific to lunch boxs. Safety and its primary function carry more weight than nice-to-haves.
Score breakdown
The bottom line
Here's what we'd tell a friend
What you should know first
This is BPA-free plastic, not stainless steel — so if avoiding all plastic food contact is your priority, this isn't your box. But at $30 with a 9.5/10 Ease of Use score, it's the easiest lunchbox for small hands to open independently.
Go for it if...
You want the easiest lunchbox for your kid to open — 9.5/10 Ease of Use with click-lock design
Tops the category on ease of use (9.5/10) — worth checking insulation performance before buying.

Renee's Take
We dug through 32 reviews — the kid-friendly dual-latch closure earns a 9.5/10 on ease of use — even 4-year-olds open it independently, 5-compartment layout fits the full lunch rainbow — but BPA-free plastic doesn't insulate (4.5/10), making this the $29.99 right pick for preschool families who pack dry snacks and sandwiches and need something kids can operate themselves

Care & Tips
Keep your Bentgo Kids Bento Box performing at its best
Wash all compartments with warm soapy water after every use — food residue left overnight causes stains and odors that become permanent.
After each use~3 min
Remove and wash the silicone gasket or seal around the lid separately — this is where food particles and mold accumulate most.
After each use
For stubborn stains or odors, soak in warm water with baking soda for 30 minutes before scrubbing.
As needed~30 min
Store with the lid slightly ajar when empty so air can circulate and prevent musty odors from building up.
Avoid using abrasive scrubbers on stainless steel compartments — they scratch the surface and create microscopic grooves where bacteria can hide.
Check latch mechanisms and seals regularly for wear. A degraded seal means leaks in your bag — replace the gasket annually or when it shows cracking.

Nothing ruins a day like a soaked backpack. I test every lunchbox upside down before it goes to school.

Food safety is the real question — it's not just about taste, it's about cold items staying at safe temps through lunch.

●I cannot deal with mold traps in lunchboxes — wide openings and dishwasher-safe construction are non-negotiable for me.

If my kid can't open their lunchbox, they won't eat — child-independent latches matter more than adults realize.

A $40 stainless lunchbox that lasts 5 years is better value than a $10 plastic one you replace every year.

●Lunchboxes take abuse — drops, slams, and daily washing. The hinges and seals are what fail first.

Dimensions matter — a lunchbox that doesn't fit the school bag isn't a real option.
