Am very happy with ours. He stops when it hurts with what he's doing and adjusts what can. Sometimes will do putting back little at time if too much inflammation
there are good chiropractors out there. I go to one that's really good who does actual testing of the spine to see where it is and adjusts it back to where it should be.
Probably would help back and hips if my fat butt would lose some weight and replace my shoes to better support arches
