I am selling this item because I received it as a gift. It is new and unused, but I did test it to make sure it works before listing it. Size: 20*24.5cm Power Consumption: 1200W Maximum Airflow: 14.6m/s Adjustable: 3 levels High Airflow It reduces noise, is easy to clean, and is durable. With an amazing amount of airflow, it dries hair faster, with a maximum airflow of 14.5m (cubic meters) per second, shortening hair drying time. Blue Light Negative Ions The external ion outlet protects the moisture of negative ions from heat, using a moisture-saving method that increases hair moisture and keeps the scalp healthy. Using it for a long time can improve the shine and softness of the hair. Overheat Protection & Constant Temperature Equipped with an intelligent temperature control function, it automatically turns off the power when overheated. It uses a temperature-reducing function, and because the heat conduction is uniform, it also protects the hair from damage. Thank you for looking.
