What are the differences in core functions between the two models? How to choose based on needs?

Hello! The main difference lies in the red light therapy function:

- USB-powered model (KL-U01): Equipped with air pressure massage, heat therapy, and vibration functions, without red light. It is suitable for people sensitive to light (such as glaucoma patients) or those with limited budgets, focusing on basic hand relaxation.

- Wireless charging model (KL-W01): In addition to the functions of the USB model, it also features 650nm red light therapy (promoting blood circulation and reducing inflammation), making it suitable for those in need of deep tissue therapy (such as those with joint strain or severe carpal tunnel syndrome).

- Purchase recommendation: Choose the USB model for better value for money, and the wireless model for comprehensive therapy.
