How we reached each verdictThe numbers behind each model's score
Dyson Supersonic
We analyzed 16 expert sources, 13 of them hands-on, and 537 owner comments, 451 first-hand, and the picture is strongly positive: experts score it 87 and owners 82. Owners most often praise its light weight (27%) and fast drying (25%), while experts repeatedly highlight its heat control, frizz reduction and magnetic attachments. Reliability is the weaker spot at 64, with 14% of owner comments mentioning failures, 6% saying it broke or died and 5% citing cord problems; long-term durability data is thin, and one expert noted it is not yet proven. Value splits owners almost evenly, with 10% calling it worth the money and 9% saying it isn't.
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.
