Those who like a try Blackroll times and do not feel like the same 30 to lie without even knowing whether you like one who is here well served. the role is very stable and are only minimally after, the hardness corresponds to the part of a normal black roll (there is an extremely hard but with the version you should not really enter) has done at the beginning saumäßig hurt this role to use, lies down after calming less than a week, for me it has achieved the desired effect, and my hip pain are gone now.
