I love this thing. I've only had it a week, and it's the only one I've had so I can't compare it to others, but it feels great. It does hurt in spots, but feels like a deep tissue massage. It's great on the upper back/shoulders and legs. It will take time to evaluate the stretching and flexibility aspect, but it makes sense to me. Similer to a rolling pin rolling out dough. You tube has demo's.Mine cost $23, I think. Try one.
