This Entil weighted heating pad uses energy-saving carbon fiber electric heating wire for faster heating and better heating quality. The far-infrared rays it releases can bring heat into the deep layers of the skin, improve the body's microcirculation, allowing you to feel the fatigue relief brought by the heat from the inside out, and help relieve muscle soreness, stiffness, muscle spasms, and chronic fatigue. The 2.2-pound weighted weight and positioning buttons place the heating wrap securely on your shoulders and back. 6 heating settings (104-140°F) and 4 auto-off timers (0.5/1/1.5/2H) to meet your different needs. At the same time, during use, the controller's display will display a countdown in minutes, allowing you to keep track of the heating duration. The heating pad is made of crystal super-soft fabric with higher gloss, smoother feel, and thicker texture, giving your skin the softest and most comfortable feeling.
