After watching countless videos I decided to buy. Glad I did. I use it before bed every night so far and I see a difference in my shoulder. I have bad inflammation from a wreck years ago and this helps.
So far so good. I've been searching for a solution to my chronic back pain, following surgery a year & a half ago. Nothing has worked. I have high expectations that this red light therapy will be my answer!
Received factory new as gift. Light function mode 850 does not turn-on.
