This is the arm and leg massager with a gentle yet invigorating side-to-side motion that soothes sore muscles and helps relieve stress. The device can be placed on the floor, table, or couch and users simply place their arms or legs on the massage heads and the unit delivers side-to-side massage that is easier on joints and tender areas yet relaxes tight, tense muscles while improving circulation. The massager has two interchangeable sets of massage heads—one set that is flat with 12 rubber nodes that knead muscles in the calves, thighs, and feet and another u-shaped set for massaging the thighs, biceps, and forearms. It can also be used on difficult-to-massage areas such as the knees and elbows. The massager has three levels of intensity, 10-, 15-, and 20-minute massage programs, and generates only a subtle hum. Plugs into AC. 25" L x 10" H  x 9" W. (10 lbs.)
