The Beurer MG-90 Metal Line Pro Infrared Massager features two powerful tapping massage heads for optimal effectiveness. The body massager is presented in a high quality chrome finish and heavy duty motors are designed for longevity and high usage. The massage speed can be adjusted in 5 steps and there are 4 separate massage programs for you to try (start, active, refresh and relax). In addition, the application of infrared heat reinforces the effect of the massage delivered not only by warming the surface of the skin but also by promoting circulation in the area. This enables the massage to reach deeper layers of tissue and muscles aiding the natural healing process.
