Designed like little ice cubes that click together to attach, all you have to "un-click" a cube from the rest in the freezer, defrost in microwave, serve food straight from the pot and viola! I find this really convenient since I usually freeze concentrated soup stock which I use to add to porridge for that added nutrition and taste for the kids.I love the fact that the little pots click on and off easily. Its "lego-like" design means that you can configure it any way you like and even stack them up to optimise your freezer space. Each blocks is designed with easy open lids that lift up but also close firmly so it is great for travel without having to worry about spilling. Plus there is a pen included for you to write what you have freezed (important cos all frozen food look kinda the same!).
These portioners are wonderful to have when you are weaning as it conveniently stores pre-prepared food purees neatly in the freezer and all you have to do is "unclick" and pop in your diaper bag when you are planning to go out. The lids also keep out potentially unpleasant fridge odour from your precious baby food. Neat!
