Query: Great product !

I've used this lunch kit several times & it's really lived up to expectations. It keeps food warm for hours & I use it when I have to take lunch to a place where there's no microwave available. I can also fix nice healthy meals which conform to my Weight Watchers program. I just fill the big container with boiling water to preheat it & heat the hot food in the bowls. The instructions say to preheat the bowls with hot water for a few minutes & then add heated food but that takes up too much time & means using more dishes so I just heat the food in the bowls which,of course also heats the bowls. The carrying case is very good & has outside pockets for condiments or whatever & a "spork" (cross between a spoon & fork) is provided & has its own holder inside the case. I really like this "Mr Bento" & would recommend it to my friends. Works way better than an old Thermos food jar I had.
