The maintenance of this product is performed by a qualified second-class electrical engineer and a comprehensive home appliance engineer, a seasoned professional with over 2,000 Dyson dryer repair cases, so you can use it with peace of mind and comfort. Even just the maintenance alone would cost around 10,000 yen if you asked a repair shop, so it's a great bargain! The main unit has been overhauled, and the circuit board, heating element line, thermostat, motor, filter, and power switch have been maintained. The front silver ring has been polished. Repairs for wire breaks and measures to reduce wire breaks have been implemented. Filter cover looseness has been adjusted. We have confirmed with measuring instruments that the temperature and airflow are equivalent to new. There is no difference compared to the later models. The items for sale are the main unit and one attachment. The head has many scratches. Please assess the other conditions from the photos.
