It's a quick and efficient kettle but thought the keep warm button would come in more handier but it doesn't. It keeps reboiling to get to the desired temperature but if you've put it at max temp you can't choose to keep it warm at a lower temp, not until the kettle has cooled down. Then as soon as you turn it on it starts boiling to max temp so you have to be quick at choosing a lower temp and the keep warm button. It's fancy and does the job and I've paid for it to do the fancy stuff but at the minute I think it's pointless and should have just bought a cheeper basic kettle.
