My wife has controlled Rheumatoid Arthritis and getting ice cream out of the container used to mean Micro Wave the ice cream so she could get it out with a spoon. You plug in this tool and in a moment or two it is warm enough to make the effort easier. It is not a hot knife, but it is hot enough to make the scooping better. It was one of her favorite Christmas gifts of 2010.
