Seemed like a good idea but it is far from it. It constantly keeps boiling. You can put it on to sleep mode but then that means you can’t get cold water. You then turn it on to get cold filter water but then it stars boiling again and by the time you have filled a glass it’s near enough boiled when you don’t want it to. It states that it is environmentally friendly but how can this be if it constantly boils every couple of minutes. We mentioned it to customer services but they were not that bothered. The filters are just too expensive so we have gone back to a good old fashioned kettle. They look good but they are definitely not worth it the money.
