Finishing my first full week of use. Was skeptical before purchasing, but the guarantee sold me on trying it. After two days of use, I still had doubts. But now, one week in with daily use, I’m no longer a skeptic.
A couple of key points. Use it on bare skin. I’ve had two back surgeries in the lumbar area. So I line the lights up there. I also find that using the units after 10 minutes on the foam roller really seems to help.
Results? After one week, my chronic back pain and stiffness are about 50% better. Looking forward to continued use and improvement.
