The pressure sensor is the feature that justifies the price, because brushing too hard is the leading cause of gum recession and almost nobody knows they are doing it -- a light that turns red is more useful than any number of cleaning modes.
Full details →Who the Dyson Supersonic Hair Dryer is for
Buy it if: Anyone who heat-styles frequently and wants temperature regulation rather than raw power.

Buy it if: Anyone with gum recession or who has been told they brush too hard.
Avoid it if: Anyone unwilling to spend roughly Rs2,000 a year on replacement heads.
