Input:
Helped cure my tennis elbow from too much time on the laptop.  I felt no results the first week at all and was getting discouraged as others claimed immediate relief of pain it took about 10 days and them it continued to improve now I rarely use it but know I should keep up with it to maintain strength in my problem arm.  Don't waste money on boughs products and physical therapy none of that helped much.
