I guess from the packit website the pros for me would be no ice packs, you don't have to worry about storing lunch boxes or them taking up space on your counters the cons since you freeze the entire bag you can't put hot stuff in it because it will be cold come lunch time,
most bags cost less and keep foods cold long enough for what is needed for school age kids. It might be nice for long days out like the to the beach or if your child has after school activities and needs to keeps snacks cold longer.
