Deeply relieves knee discomfort: This FSA-compliant knee brace offers three optimal temperatures for the human knee: 45C, 55C, and 65C (110F, 130F, and 150F). It also features three modes of scientifically formulated vibration massage to further relieve knee pain. Please select the appropriate heating and vibration mode based on your knee condition. Adjustable size for multiple body parts: More than just a heated knee brace, it comes with two extension straps, one long and one short, allowing you to use the heating pad on other parts of your body, such as shoulders, elbows, and legs. The Velcro edge design allows you to adjust the size to fit your knee shape. Please ensure the size is correct before purchasing, as everyone's body shape is different. Wireless knee massager: The controller is also the battery. A full charge takes 23 hours and provides 13.5 hours of continuous use. Power consumption will vary depending on the mode and intensity selected. We recommend using it for 15-30 minutes each time. Easy to operate: The upgraded touchscreen design eliminates concerns about overly sensitive buttons or complex settings. These heated knee braces feature a large screen displaying temperature and battery level, and each operation has a corresponding button.

The colors are unisex. A perfect everyday gift! Suitable for Christmas, Thanksgiving, Mother's Day, Father's Day, and Valentine's Day.
