OK, I'm baffled by this product. How are they different than taking various sized plastic or glass containers in a lunchbag to work/school? The containers look awfully small too (maybe I just eat too much, LOL).

Often I throw leftovers into lunch-sized plastic or glass containers and freeze for myself and the girls for lunch. If you use the LTLB, you'd have to take the food out of the storage container and put it in the LTLB container. Seems like a waste to me.

I'm NOT being critical of those who choose to use this product, but I'm scratching my head over it....
