Thank you for viewing. 1300W Negative Ion Hair Dryer Foldable, 3-stage adjustment Purchased in 2023, used for about 3 months, and then stored in its box. I started using it again about six months ago and it was working normally until recently. Regarding the defect: The switch is difficult to turn off. The trick is to turn it off slowly, but once in a while, the switch doesn't return and remains on. It works without problems, but please understand that this is a "defective item." There is no instruction manual. It will be shipped in the box shown in image 3 (the original box).
