The Dyson Corrale is a cordless hair straightener that uses flexing manganese copper alloy plates to shape around hair, allowing for styling with less heat and reduced damage. It offers the thermal performance of a corded straightener while providing up to 30 minutes of cordless use, with three heat settings (165°C, 185°C, 210°C) and intelligent heat control. The device also has a 70-minute full recharge time, an OLED screen for battery and temperature status, and can be used for both sleek styles and curls.
