How we reached each verdictThe numbers behind each model's score
Dyson Supersonic r
Our research covered 8 expert sources, 6 of them hands-on, plus 533 owner comments. All 6 hands-on testers praised its light weight, and 5 called it fast-drying. Lightness is also the top owner theme at 44%, with fast drying at 27%. Every expert flagged the price, and 3 of the 6 hands-on testers would steer most buyers toward the cheaper Supersonic Nural instead. Reliability looks solid but not spotless: 9% of owner comments mention a failure of some kind, including 6% citing cord issues, and we found no recalls. The evidence on published scores is thin, with only 2 available.
ghd Helios
Our research found strong agreement on speed: both hands-on reviewers rated it among the fastest dryers they've used, and 11 of 98 owner comments praise quick drying, versus 2 citing slow drying. Value is the biggest owner sore point, raised in 13 of 98 comments, which helps explain the gap between the expert score (78) and the owner score (65). Reliability looks good, with failures mentioned in only 4% of owner comments and no recalls on record. The evidence is thin, though: only 3 expert sources (2 hands-on) and 45 first-hand owner accounts, so overall confidence is low.
Shark FlexStyle
We analyzed three hands-on expert evaluations, one based on nearly two years of use, along with 573 owner comments, 494 of them first-hand, plus about 3,700 retail ratings. All three experts call it well built and effective, especially as a dryer, and owners most often praise its value (13%) and fast drying (13%). Complaints are scattered: 5% of owners mention noise, 4% feel it's poor value, and only 3% of comments mention failures, which supports a strong reliability score of 92. The evidence is thin on the expert side, with only three hands-on assessments and two published scores, so our confidence is medium.
