Fast to heat water and other liquids, small and easy to use. You need pots that are compatible, and they will heat the food differently than other heat sources, but for heating pot of water for pasta or a soup, this works great. Super fast. Boil water for eggs in half the time or faster. It is noisy, sort of a whine, but best to leave the kitchen for a few minutes and come back to a boiling pot of water in surprisingly short a time.
