Input:
I was getting depressed because I thought I would have to give up tennis which I have been enjoying for 15 years (45 now). Had tendonitis on both arms for 5 months. 2 weeks with the Flexbar and it's almost gone. Only hurts immediately after playing but by the next day the pain is gone. I used the red for 1 week, the green for the 2nd week and I am now starting the 3rd week with the blue. When the red arrived the pain was so bad I could barely twist it even though my 11 year old can twist it easily. Within a week, the red was too easy. The green was tough and still caused some discomfort. Now after a week of that, the green is soooo easy and no pain. Started the blue yesterday and I can do with almost negligible discomfort. The inventor of this product deserves a medal.
