This is the first one of these I've bought. I'm using it to put left-overs in and the portion size of the compartments make it just perfect for lunch. It's so easy to put this in the microwave and have a healthy and quick lunch, It's dishwasher safe so that's another plus. I'm loving using this. I will buy more. They are a little expensive, but I believe over time they will pay for themselves in saved lunch money, aluminum foil and saran wrap.
