This Electronic Pulse Massager is equipped with advanced TENS technology to quickly relieve all types of pains caused by strain and trauma—from backaches to stiff necks, carpal tunnel to foot discomfort.

It’s completely comfortable and safe! Includes 5 auto modes, 3 selectable massages and a LCD screen. Uses 4 AAA batteries, included. Replacement pads are also available. FDA-registered.
