I received the Shiatsu Neck & Shoulder Massager free of charge for my honest review. The Massager works really great and its super relaxing. The Massager stays plugged into the electricity or car lighter to work both adapters are supplied. The Massager can be used with heat or without it can move one direction or go in reverse. There are two sides to the Massager each with two large and two small balls on each side, the balls move around in circles. You can put as much pressure as you want with the Massager just by pulling in with the Positioning Handles. This Massager is not one that you can lay on as the Balls are hard, you place or lay it where you want and give position and pressure needed. I highly recommend the Shiatsu Neck & Shoulder Massager that can be purchased on Amazon. Thank you, Jerri #1byone
