This is the neck massager that provides penetrating, deep tissue or soothing, light pressure massage. Unlike typical neck massagers that only provide vibration, this model uses two rollers that rotate in two directions to simulate the kneading of the human hand for focused, deep pressure that releases trigger points around the cervical vertebrae or for gentle pressure similar to Swedish massage. Ideal for providing relief from muscle pain and strain brought on by everyday activities like driving, flying, or office work, the massager is made from comfortable foam, sculpted to fit comfortably around the neck. Two pull handles allow you to compress the massager against specific areas of your neck and shoulders. Massage style and intensity is managed using the attached hand-held controller. Plugs into AC or a car's DC power with included adapters. 12" L x 12" W x 7" D. (4 1/4 lbs.)
