I use this daily for lower back pain. The light along with the vibration helps lessen the discomfort. It is easy to use the control and to strap on the belt. This is my second LifePro product. I like the quality.
I had a long day of strenuous activities & my back was aching. My belt just arrived so I opened it to use & am so glad. Today I feel good & I would usually be pretty miserable.
