How does the Careella Wireless Knee Massager work? The massager combines adjustable heat and vibration to relax muscles and reduce knee discomfort. Heat helps relieve stiffness, while vibration improves circulation. Its wireless design makes it easy to use at home, in the office, or while traveling. Can the heating and massage functions be used separately? Yes, you can use either function independently. Choose vibration massage for muscle relaxation or heating for warmth and comfort. The adjustable settings allow you to personalize your experience based on your needs. Can I use the massager if I have a medical condition? If you have joint, knee, or muscle conditions, consult a physician before using this device. It is intended for general relaxation and temporary discomfort relief but is not a medical treatment or a substitute for professional care. Can the massager be used while moving? No. The massager is designed for use while seated or lying down with the knee bent. It should not be used while walking or engaging in active movement to ensure proper positioning and effectiveness. Is the massager suitable for larger knees? Yes, the XL model features extended straps for a secure and comfortable fit. The massage coverage remains the same, but the adjustable straps provide better support for users with wider knees.
