Works pretty well. Much easier than using the boiling water, faster too. Only complaint is the lack of "Cook" and "Keep Hot" labels, instead they have two icons, which I guess we are suppose to memorize. I use it once in a while and always get confused which side to set it to. Why not put labels with the icons? I had to put the labels using a permanent marker to prevent from having to refer to instructions before each use. Purchased in Jan 2005, still working well.
