The key feature is instant hot water. It's versatile in that the same tap also delivers chilled still water and sort-of but not very sparkling water as well as domestic mains water and hot water. However, there is one obvious design fault in that the swan neck does not reach far enough into a large sink. The washing up liquid dispenser is a complete and irritating waste of money as its neck only just pokes out over the sink. Is the device worth it? Yes, if you can afford it, because when you want a cup of tea you've got boiling water available instantly.
