I confirmed it powered on, but I left it unused the whole time. TESCOM Curl Dryer, Negative Ion, Lightweight, 22mm, with Brush, Easy-to-Remove Plug, Hair Dryer, Pink, TC330A-P Includes a wide catch brush and a 360-degree pin aluminum roll iron brush. By using the brushes separately, you can achieve a wide range of styles, such as adding volume to the roots and creating defined curls. The wide brush firmly catches the hair. It creates hairstyles that lift from the roots. The brush tip is slim and easy to insert between the hair, allowing for smooth styling. This brush is made of aluminum with 360-degree pins and good thermal conductivity. The soft, ultra-fine nylon pins firmly catch the hair. Recommended for creating defined curls at the ends of the hair and styling bangs. *This is a comparison image of curl strength based on the presence or absence of aluminum material. There are individual differences in the "formation" and "hold" of curls. You can change the direction of the brush in four directions (front, back, left, and right) to suit your usage and dominant hand.
