Say goodbye to saggy arms. The Underarm Toner emits micro electric currents to stimulate arm muscles for a sleek, toned look. Using Electrical Muscle Stimulation (E.M.S.), it contracts muscles automatically, replacing traditional exercises. Use it 15 minutes a day for slimmer, more toned arms in 1 to 2 months. Features 10 training modes and adjustable intensity. Not for use by those with a pacemaker.
