It's perfect! The four removable compartments keep different bits of lunch separate, and you can remove two of the compartments if you want to bung a big sandwich or cutlery in. DD (4) has been VERY pleased with her lunches (as was DH, 34 ).
But you can take two compartments out if you want to include a sandwich. Drinks bottle gets carried separately, but none of the other boxes I saw could fit a drink in. DD has a little tote bag to carry the box + beaker.
It's only a fiver...that's pretty cheap isn't it? Or at least it's cheaper than the "Laptop" lunch boxes that I was considering.
And it's all dishwasherable and microwaveable. <<foot in door>>
Hmm...wrt transparency, I do provide uber-gorgeous lunches. <<preen>>
(disclaimer: I'm massively pregnant and my nesting instincts seem to be centred around dinky lunch goodies...give it another few weeks and DD will be lucky to get a philly sandwich and packet of crisps...decanted into a compartment, natch)
Haven't got this lunchbox but have loads of other Lock and Lock boxes, several years old and never had a problem with the popper lids. I threw away all my cheaper versions when I discovered there was a brand that didn't keep popping open. They have some sort of guarantee about the boxes as hinges are tested to be opened a gazillion lot of times.
