Built-in Precision Lighting & Ergonomic Handle: Assistive LED lights illuminate instantly, revealing foot details clearly. Curved handle design ensures a secure, comfortable grip with anti-slip properties. Rechargeable and Portable Design: Features a long-lasting built-in battery and a convenient Type-C charging port. Its compact size makes it perfect for travel, on-the-go care, or neat storage. One-Button Simple Operation: Control everything with a single wheel—press and hold to turn the power/light on/off, scroll to adjust the speed. Operation is extremely convenient.
