Only available from Hammacher Schlemmer, this is the wearable cordless device that combines electrostimulation with heat therapy for drug-free relief of neck stress and tension. Employing transcutaneous electrical nerve stimulation (TENS), an approach widely embraced by physical therapists and other medical professionals, the device delivers harmless electrical pulses to the neck to block pain signals from reaching the brain. Its heat setting delivers soothing warmth up to 118° F that helps loosen knots and speed circulation to relieve neck pain and stiffness from driving, flying, or office work. The u-shaped band slips comfortably around your neck and the included infrared remote lets you create a customized 15-30-minute treatment session by selecting from six modes, 16 intensity levels, and two heat settings. Rechargeable battery provides up to 21/2 hours of use with the included AC adapter. Not for use with pacemakers. 6 3/4" L x 5 1/4" W x 2 1/4" H. (7 oz.)
