Overview
Smoothing bedhead before a video call or in a hotel room is the job here, with MCH heating and ceramic bristles that warm up in about a minute. Charging runs over USB-C at home or in the car, and the brush cuts power when idle.
Quick warm-up and a long charge make it practical for days away from outlets. Ions and ceramic bristles reduce flyaways after workouts. The spec table caps heat lower than the top setting in the bullets, so buyers with coarse curls should treat full heat as uncertain.
Who it's for
Car commutes, short trips and pre-call prep are where it earns its place. Owners of very coarse hair who need a dependable high heat ceiling should check the unit before relying on it.
Pros and cons
- About a minute to heat
- Several sessions on one charge
- USB-C car charging
- Ceramic bristles cut friction
- Peak heat figures disagree
- Size figures disagree
- Idle shutoff time not listed
Performance notes
Ceramic bristles carry heat from the MCH element while dual layers reduce drag through tangles. Smaller sections and slower strokes let hair absorb enough heat to straighten. The battery supports several short sessions rather than one long styling run.
