Three children and over the years I've despaired with lunches. We've tried just clingfilm (resulting in squashed sandwiches), we've tried lots of smaller KlipIt boxes for seperate items (they have mostly got lost), then I came across these.
We've been using them since last September and so far mostly good. The catch has broken on one of them but it is still usable.
It keeps everything seperate, so I can send along a sandwich, with salad, carrot sticks, fruit etc in the other compartment. The main compartment will hold a carton drink if necessary and anything else you may wish to send along, cheese, small yogurt etc. We've also put pasta salad in the main compartment and filled the smaller ones with other things.
They are very easy to clean. Warning though, if you have things that might drop out, you need to teach the child (if they are quite young) which way to open it. I got around this by sticking my daughters name label on one side, telling her to make sure she can see her name before opening it.
Total thumbs up from me. I now don't have to battle with clingfilm every day or have a drawer full of numerous tiny boxes.
