I've only used this product a week and I can say that the red light works well. I like the timed feature. I am excited to see what continued use looks like since a week is too soon to tell.
I purchased one for myself and one for my daughter. Used for the first time today and just the warmth of the lights felt very good on my back, can’t wait to see once I get to use it daily.
I got this to use for lower back pain. I have also been dealing with a pinched nerve in my upper shoulder. So I decided to try it on that. In a matter of a few weeks, my nerve pain is so much better that I am thinking that it is resolved. I have had this for several months and I was planning to see a chiropractor. Well, the belt has already paid for itself by saving me from seeing a chiropractor.
