My daughter used this for eight months. I am selling it because I bought a new one. This is a convenient item for even elementary school students to dry their hair by themselves. It's also recommended for those who want to dry their hair quickly! The main features of this product are as follows: Quick-drying performance: Equipped with the unique quick-drying technology "Drape Flow X4," which delivers air over a wide area by separating the hair in a three-dimensional manner, enhancing quick-drying performance. The airflow is approximately 7.4 m³/min. Plasma cluster: Positive and negative ions wrapped in water molecules coat the surface of the hair with moisture, suppressing static electricity and friction damage. SENSING mode: Measures the distance between the hair and the dryer with a distance sensor and automatically controls the air temperature to keep the hair surface temperature below approximately 55°C, protecting the hair from heat damage. Compact design: The motor is stored in the handle, resulting in a compact and lightweight body, reducing strain on the wrist. Modes: There are seven drying modes: HOT, SENSING, BEAUTY, SCALP, COLD, GENTLE, and APP (app compatible). Thank you for viewing.
