"I am 78 years old and am part of a small group of women that knit blankets for poverty babies. As I get older, naturally I have more aches and pains. My right arm and hand is painful due to over usage (that is what my doctor said). I am not one to use "gimmicks". Therefore I was skeptical of this product. I am now a believer. Rarely do I have any pain in my arm or hand and I still knit several hours each day. "Vivian, Texas
