I received one of these about 4-5 years ago as a gift from a family member.  At first I was a little hesitant to use it, but after using it just once I now use it all the time.  I mainly use it to heat up my soups, gumbo, or any other rice dish that I might be taking for lunch.  Because I use it all the time and my coworkers ask about it, I decided to buy 3 more as gifts this year.  

It isn't a huge size, but that's okay as it is just big enough for a lunch-size portion.  It heats up my soups better than sticking a bowl or container in the microwave.  What I like about it is that it heats everything evenly without bowling over in the microwave.
