Hi Richard, Thank you so much. The Advanced Technology 7 Wrist Health Strap works extremely well. I had carpal tunnel and boy, that was painful as I've never had it, yikes. I could immediately feel the energy at work and it felt awesome. I'm much better now because of the Wrist Health Strap and still not doing anything major. I had gotten the carpal tunnel due to doing my Reiki massage, which is hands-on-healing. An excellent product, thank you, thank you. Love, Light & Many Blessings to YOU D September 18, 2019
