Used for about two and a half years, from August 2022. Operation confirmed. It rattles when shaken; I'm not sure if any parts are damaged inside, but I've been using it normally for several months without any problems. It was incredibly easy to use, and I cherished it. It was the best hair dryer I've ever had, but unfortunately, I'm selling it because it's too heavy for my child to hold. Used item; please consider this before purchasing. Those who want parts are also welcome. ↓ Product Description Fast drying with Panasonic's maximum airflow*1.
