Great for shins and back. Great design.
Long story short held together with ducttape and gorilla glue. I bring it with me everywhere. Work, gym. It gets used well multiple times a day.
Delivered quickly. The ridges cup and cradle muscles and ridges of soft tissue without irritating bony protuberances. Gonna buy more.
Love the hard roll-ga. My vertebrae are very sensitive (think get ripped open on water slides) and the roll-ga is perfect for protecting my spine while allowing me to roll out my muscles
Just put my original foam roller in the back closet and the Rollga is now front & center!
