Introducing the R8 Plus. We've taken everything we've learned over the years and designed the next evolution of R8. Dial in the perfect amount of deep tissue massage force with the adjustment dial. With a Patented integrated mechanism hidden in the frame we designed the R8 Plus to be easy to use, reliable, and built with the highest quality of materials. Use the adjustment dial to reduce or increase the force as needed for the perfect feel. An FDA Registered Medical Device, the R8 Plus targets the IT-bands, quads, hamstrings, calves, shins, gluteus, arms and more. It takes the work out of rolling and is compact enough to take anywhere.
