My husband and I bought this product 2 years ago. We have both used it for various aches and pains. My husband has problems with a joint in his arm due to an old sports injury. He uses the Willow Curve 2-3 times, and it alleviates the pain for quite awhile (days, sometimes weeks). I have also used it numerous times for tendonitis and muscle pain.
We both love our Willow Curve.
Bottom Line: Yes, I would recommend this to a friend
