This is the wireless foot and leg massager that gives tired and achy lower limbs a deep pain-relieving heated massage. Two therapeutic heat settings and three air compression intensities improve blood circulation, alleviate fatigue, and help move fluid build-up away from the legs. Choose one of three preprogrammed modes or customize settings for a personalized relaxation experience. Because this massager is lightweight and cordless, you can enjoy a rejuvenating massage whenever and wherever you need it. Its rechargeable lithium-ion battery provides up to 90 minutes of warmth and massage on a full charge via USB. Adjustable hook-and-loop fasteners fit calves 22"-28" in circumference. Suitable for use on either leg. 11 1/4" H x 5 3/4" W x 6 1/2" D. (2 lbs.)
