Four years ago I bought the Willow Curve in 2015 for $619.00 for my son who had severe knee pain. He used it for a while with no relief. He gave it to my other son, again with no relief. Four months ago I tried using it for knee and shoulder pain with no relief. I will admit that none of us used the device religiously for months. I doubt that most people will when you can get a steroid shot and usually get quick pain relief. And, I can get a lot of shots for $619.00. Bottom line, based on my experiences, it's a waste of money. Today, I'm trying to contact their customer support, and their chat is not responding. I just want to send the device back, no refund, no credit, I just hate to throw it in the garbage.
Bottom Line: No, I would not recommend this to a friend
