I already owned one and decided to buy 3 more because they are so essential for someone like me who has food allergies and takes food everywhere I go.  I have one that I keep at work, one for home, amd two for traveling.  I can plug one up in my SUV and have hot food on road trips and in the hotel room for a meal.  I can easily take one or more with me when visiting friends and family, plug it in, and when everyone else starts to eat, my hot course is piping hot and ready to eat.  I love putting my Rosemary Potato Chowder with Polska Kielbasa in there.  Delicious. I accompany that with a salad and my meal is complete.  I love my Lunch Crocs!!
