AMAZING!!! It works to noticeably reduce pain & stiffness for me and my wife. Triple bonus is that it has reduced symptom of neuropathy in my feet allowing me to reduce medication use, plus my thinking seems to be clearing up and memory improving. We look forward to learning more benefits and ways to use. Update, recetly fell and used this to treat soreness and swelling, which was extremely effective. Also, did the normal alernating Ice/Heat, but the difference Red Light therapy made immediately after use and still the next day at work was extraordinary. We are believers.
