The BM 508 Powerball Duo Vibrating Massager with Cover from Body Sculpture is ideal for relaxing tense muscles. Its special design makes it easy to focus on a specific muscle and concentrate the pressure of your body weight on that spot. Thanks to its intense vibrations, the massager quickly relieves pain from tense muscles. You can adjust the vibration speed to three levels, depending on the pressure you prefer. The Powerball Duo effectively helps relax the back, neck, feet, calves, shoulders, and hips. The device is small and lightweight, making it easy to take with you anywhere. This can be especially useful on long car journeys or sitting in front of a computer. Using the roller will quickly relieve neck pain after prolonged periods in one position. This massager is useful for everyone. It can be used to relax muscles, warm them up, and prepare them for physical activity. It's battery-powered, providing up to 50 minutes of continuous use per charge. The massager comes with a special drawstring pouch that allows for massaging hard-to-reach areas.
