Dyson Supersonic Hair Dryer vs Laifen Swift High-Speed Hair Dryer
Which should you buy? Our verdict on both, pulled from our full The Best Hair Dryers: 4 Compared (and One to Skip) comparison.
The Dyson Supersonic is the fast, light, handle-balanced benchmark of the group, with intelligent heat control and five attachments. If its flagship price is a stretch, the Laifen Swift delivers most of the everyday experience, with a 110,000 rpm brushless motor and 100-times-a-second temperature control, for a fraction of the cost.
