I bought this for my husband who is a diesel mechanic to warm his lunch at his tool box station while he works - he loves it! He takes frozen food, usually rice and meat, and by lunch time he's ready to go. No microwave- no dried out, nuked food. He's had all the guys gathering around asking where to get theirs since it's such a novel idea! I also bought 2 more as gifts for my mother and sister in law - they both also love it! I think I'm gong to order the hubs another one because he also likes to take frozen California veggies and warm them in butter with seasoning. Such a convenient product, and it's been fun to come up with new ideas for it too!
