Unlike many other lunch style boxes, the go2 container seals off each compartment. You can literally fill each compartment with different colored water, shake it and not have the colors mix. This was no easy feat. But nobody likes having their sandwich soggy because some sort of sauce or juice flowed into that compartment. There are also a few lunch containers that have lids for each compartment. This creates a lot of cleaning and a high probability that lids end up getting lost.
