I warm my fingers in front of the climbing on it. I train my fingers a little when I got my hands free. And the green ring could also be used as a little rehab measure aims (but would be for real finger injury but rather a soft ball to start better). But by the way, is not at all so the whole point of this product. So: 1a wonderful. does not stick, lößt not to be. makes no noise ... top!
