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.
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 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.
