They work, but needs stronger material.
So far I think these containers are ok. Each compartment holds a decent amount of food. They hold up well in the freezer and in the microwave. I was even able to microwave with the lid on and it did not warp. My only problem with these containers is that they are not made out of a flexible enough material and the lids and plates are prone to crack or break if you are not extremely careful. One of my plates did arrive with a chip on the corner of the lid. These seem to be leak proof so far, but in order to acheive this you must make sure that the lid is on tight. Each side must be slowly pressed so that you here a click from each of the tiny clips that line the lid. Press up and down the sides of the lid until you don't hear anything snap and your tray should be sealed. Opening the lid is very difficult because if you are not careful the lids or the tray will crack or chip. I have 3 trays to chip or crack since I purchased these containers. I like the concept of meal prep and these containers work for what I need for now. I do wish they were made out of a stonger material.
