[POWERFUL WIND with UPGRADE BLDC MOTOR 3.0] - The BLDC motor is a brushless motor that extends the life of the dryer more than 10 times. It not only lowers vibration but improves energy efficiency by more than 20%. The upgraded motor, wide inhale part, and internal air stream guide brought in more wind and blew out more powerful wind than the existing dryer. [15 Wind Types to Choose From] The JMW AIR SENS hair dryer operates the motor and heater independently. The motor operates only during cold wind mode. Once changing from warm to cold mode, cold air immediately comes out without being lukewarm. And the most amazing thing about it is that you can mix 5 wind speeds with 3 different types of temperatures which can make up to 15 wind types.
