Lunix Cordless Electric Hand Massager w/Compression - 6 Levels Pressure Point Therapy Massager for Arthritis, Pain Relief, Carpal Tunnel and Finger Numbness - Shiatsu Massage Machine with Heat -Black

*HOW IT WORKS: Instead of using the traditional rolling technique, the LX3 air compression massager applies pressure to the hand and wrist to help it relax and sooth the tense muscle. Use a 5V plug in order to charge the LX3 hand massager. If you can not see the red light flashing while charging or if the unit turns on for few seconds (then all the lights flash and the unit powers down), it means the plug you are using is higher than 5V or the usb cable didn’t fit properly into the usb port.
