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.
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.
Shark SpeedStyle
We analyzed 7 expert evaluations (6 hands-on) and 91 owner comments, 62 of them first-hand, and the picture is consistently positive: all 6 hands-on experts found it fast-drying, and 16% of owners say the same. Value is the top owner theme at 21%, with 12% praising frizz control, though 6 of 7 experts call it expensive at full price, and 3 flag a learning curve with the attachments. Reliability looks strong, with failure mentions in just 3% of comments, 2 of them about overheating or shutting off, and no recalls on record. Confidence is low because the owner sample is small, although the 4.3-star Amazon average across 1,600 ratings points the same way.
