This Shiatsu neck and back massager offers daily comfort and relaxation. It can be used anywhere, providing a soothing experience for the neck, shoulders, back, abdomen, arms, thighs, calves, and feet. Equipped with two massage directions, three adjustable speeds (low, medium, high), and 16 deep 3D rotary kneading massage nodes, this massager allows users to customize their experience. The convenient arm loops provide control over the pressure applied to the body, while the heating function adds a layer of comfort. Overheat protection ensures safety, and the massager automatically shuts off after 15 minutes. The massager is made of durable PU leather and soft mesh material, ensuring high quality and ease of cleaning. It includes both an AC wall adapter (110-220V AC) and a car adapter (12V DC), so it can be used at home, in the office, or in the car. Note: This product should not be used while driving. Not recommended for children under 12 years old. Not suitable for individuals who have undergone neck surgery or have metal implants in the neck or spine. The massager is not cordless and requires an AC adapter for home use and a car adapter for use in vehicles. If the connection appears loose, ensure the connector is securely attached. This is a deep tissue massager and may feel intense for those who are not accustomed to this type of massage. It is advised to place a towel between the massager and your body for added comfort.
