Bests & Worsts Reviews from Amazon

When I looked this thing up, I saw the picture and thought, “that looks like a nerf football cut in half!”. I have suffered with costochondritis for over 10 years that at first resulted in several trips to ER thinking that I was having a heart attack. This condition makes me get bad anxiety and I would not wish it on anyone. I also have upper neck and back issues that contribute as well. I read the reviews, and after reading the ones about helping with Costo I thought what is another $90 or so amongst the thousands already spent? I purchased it and when I received it found that it was actually well built. I used it as the instructions said, and immediately noticed a small change, but nothing dramatic. I am glad that I read the reviews that said to stay with it because if I had not I might have gotten discouraged and quit using it. After about a week my back and neck started to loosen up, and the tightness and dull pain from the costo started to subside. It actually worked! I am now using it every couple of days when I start to feel things starting to tighten up again. All I can say is: this is a great product (though simple) that has been life changing for me. I have not been paid or given anything for this review. I am giving this review because this device has helped me.
