This smart neck massager utilizes 4-point fixed heating design and intelligent 3D suspension electrodes to give out electric current at a minimal intensity in order to improve the effectiveness of massage. The electric pads send waves to your neck and create a sensation that really helps with the deep tissues. The skin-friendly, breathable soft silicone base makes the electrodes floating at 360 degree, and the U-shaped traction is closer to the skin, which can adjust automatically and fit tightly to all neck size. This wireless neck massager is a way to achieve deep relaxation of cervical spine.
