This is a high-power, high-airflow hair dryer with a brushless motor. I've been using it for about a week. The sound is relatively quiet and it's lightweight, so it's less stressful to use. Magnetic attachments are also included. The filter can be cleaned by yourself, making maintenance easy. By pressing the temperature adjustment button while pushing up the power button, the automatic cleaning function is activated, and the filter is automatically cleaned (this mode reverses the motor to blow away dust clogged in the filter). The power has two levels depending on how far you push up the power switch, and the temperature can be adjusted with the button below the power switch, with 5 patterns: "cold air ➡ warm air low ➡ medium ➡ high ➡ alternating cold and warm air". Please note that the outer box and instruction manual are not included. The product will be shipped in a box for a different product, but it will be securely packaged.

If we are unable to accommodate your request, we will gradually lower the price, so please "like" the item and check back regularly.
