I also bought the Blackroll Orange STANDARD (The Original), but for medical purposes has this role not geeignet.Und I have still the Sissel Pilates Small Props RollerPro SOFT bought the blue. Although is great for relaxation but not for the vortex, because far too soft.
Then I have the FA Sports Yoga Yogiplus medium scooter, blue, 15x15x45, ordered 596. The hardness is optimal and corresponds to my Bedüfnissen, the massaging action is better than the other two roles, but unfortunately this is expressed a Bissel together.
