Are you suffering from sore, stiff muscles or joints and looking for a device with long lasting battery and which does not require proximity to an AC outlet? Then six hour cordless Heat Therapy Shoulder Wrap is the right device for you. It provides deep-penetrating heat therapy to relieve sore, stiff muscles and joints without requiring proximity to an AC outlet. This one is powered by a slim, long-lasting lithium-ion rechargeable battery that ensures consistent heat therapy and does not lose their heat quickly like other wraps. The flexible, thin wrap can be worn under clothing, and it conforms to the body without inhibiting movement; the Velcro fasteners ensure it remains in place.
