This kettle heats quickly and well. It isn't as easy to fill at our sink as the old kettle was that it is meant to replace, but that is partly due to our water filter and will not trouble everyone. I am hoping it is saving electricity by heating so much faster without the stove. It doesn't have a setting to keep water warm, but again, saving electricity and adapting to a new routine with it. On the whole, a good kettle.
