The Sharper Image Total Hand Massager has innovative features and it is designed to soothe and restore hands better than ever. Place your entire hand in the soft, cloth-lined chamber, turn it on and let the built-in air bladders make all the work. The bladders inflate and deflate to squeeze away aches and stress. The Sharper Image Total Hand Massager features high and low intensity, high and low optional heat, automatic shutoff timer and two massage modes. Select basic massage (air bladders inflate/deflate in unison) or wave massage (air bladders inflate/deflate alternately to create a “rolling” sensation).
