I bought it to me, in order, to process my legs fascia-to-back, etc.. In order to give an accurate judgment, I have now used for a long time (and several times a week) and I can say it is dimensionally stable, not too soft, but not too hard. The knobs are - to my mind - not unpleasant. After "scrolling" I lie, always to relax, just a few minutes on it, which in my spine is doing very well. With my height of 1.77 that is no problem, and the 90 cm length of the roll are, especially for the fascia roll, ideal. Then there is the good price!
