I have a Zojirushi Mr. Bento. It's pretty good. Kind of big and heavy and lots of small containers inside. So if you want to bring a big salad you are out of luck. Doesn't really keep everything super hot if you want hot things. Hot things will stay warm for a couple of hours but not be piping hot by lunchtime. And if you put hot things in the bottom containers the heat will rise into the top containers which are supposed to be for cooler things, so mixing hot and cold doesn't work out all that perfectly. Other than all those bad things, it's nice when you want to bring lots of little items all separated.
