The Dyson Supersonic sits fourth in this guide and is the most expensive hair dryer in it at £299.00. The same listing carries a 4.7 out of 5 rating from 147 ratings. Its finding is unlike the rest of the ranking: there is no weight figure anywhere in its specification, so the gap between a marketing weight and a spec-sheet weight that runs through the other three entries simply cannot be checked here. What the page does give is 1600 watts, a maximum temperature of 100 degrees Celsius, and a bullet claiming it "Protects hair's natural shine. No heat damage."

Two things on the listing do not add up. The page reports 147 ratings, but the star breakdown underneath — 82 at five stars, 15 at four, 2 at three and 1 at one — totals 100. And the specification lists "3" speeds and, separately, "4" settings, without saying which of the two covers heat. Everything below comes from the Amazon product listing, price and figures included, and not from any testing we have carried out.
