I had ordered my role in the small and large version, because I did not know how I get along better. At 80 kg 1,82 m length, the longer version is much better, though of course somewhat sluggish. I use it mainly for the entire back up high above the shoulders (also along the stretch) and buttocks and legs, from all sides. It does in some places really nasty hurt, stay relaxed and keep doing that is still very good. If it were a feel pain, like an intense massage operates the bonded points. The back feels after extensive treatment significantly loosened on, I've been doing daily use beginning 2 weeks before the less back pain, am more flexible. One star deduction for the value for money - there were simply glued together 2 short massage rollers, not seamless and unclean transition of seams (hopefully longer disturbs the eye than the functionality).
