Lower back pain - does the job.
I do a lot of desk work and found by back sore all the time. I find that using this on my lower back helps relieve the pain and gives me relief. Unit has three settings and is built well. I tried to roll on it on the floor but the plastic is pretty stiff and it hurt too much. But seating in my chair where I am not putting my full wait on it works pretty good.
